Solve It on the Floor
The tools a controls or automation tech reaches for during a job. Cross-vendor translation, signal diagnosis, motor circuit sizing, trip logic, and machining math.
Cross-Vendor & Core
Translate between platforms, scale signals, size motor circuits, check trip logic, and dial in machining.
Siemens to Allen-Bradley Translator
Pick a category to see a side-by-side equivalence table. Optionally type a Siemens address to get the AB-style equivalent.
Analog Scaler
Enter a raw PLC count and engineering unit range to convert to real-world units. Detects wire-break, overflow, and underrange faults.
The raw value is inside the Siemens 0 to 27648 nominal band, so the conversion to engineering units is valid and the field signal looks healthy.
Electrical for Compressors
Select motor HP and voltage to size branch conductors, breakers, and overloads per NEC Article 430. Results are instant, cited, and ready for the field.
The conductor meets or exceeds the NEC Article 430 minimum of 125% of full-load current for continuous motor duty.
Interlock Trip Checker
Set each compressor interlock state to instantly see whether the package is ready, running, blocked, or tripped. Trips latch until a manual OFF to RUN acknowledge.
All permissives are made and no protective interlock is active. The start circuit will seal in on a valid run command.
Speed, Feed and G/M-Code Decoder
Switch between speeds and feeds calculator and G/M-code quick reference. Instant cited results.
The calculated spindle speed is inside the machine's usable range, so the surface speed and feed per tooth will be delivered as programmed.
Electrical & Safety
NFPA 70E arc flash and approach boundaries, plus NEC voltage drop and conduit fill.
Arc-Flash PPE and Boundary Picker
Enter the incident energy from the label, or pick the equipment, to get the NFPA 70E PPE category, gear list and arc-flash boundary.
Incident energy is in the Category 2 band (over 4 up to 8 cal/cm2). Arc-rated shirt and pants or coverall rated at least 8 cal/cm2, plus face shield and balaclava or hood, are required.
Arc-rated shirt and pants or coverall (arc rating at least 8 cal/cm2), arc-rated flash suit hood or face shield with balaclava, hard hat, safety glasses, hearing protection, arc-rated gloves, leather footwear.
Shock Approach Boundary Lookup
Pick the system voltage and get the NFPA 70E limited and restricted approach distances for safe clearance.
Includes 208V, 240V, 277V, 480V and 600V systems, the common plant range.
Only a qualified person with the correct PPE and an energized work permit may cross the restricted approach boundary. Maintain the limited approach distance for unqualified persons.
Voltage Drop and Wire-Run Checker
Enter the load, run length and conductor to see the voltage drop against the NEC recommended 3% branch and 5% total limits.
Voltage drop on this branch circuit is well above the recommended 3%. Increase the conductor size or shorten the run. High drop causes motor overheating and nuisance trips.
Conduit Fill Checker
Pick the conductor, count and conduit size to check fill against the NEC Chapter 9 limits before you pull.
Conduit fill is at or below the 40% NEC limit for three or more conductors. The raceway has room to pull without damaging insulation.
Motors & VFDs
VFD to motor cable length, nameplate decoding against NEC and NEMA, and power factor correction.
VFD to Motor Cable-Length Checker
Enter the lead length, motor type and carrier frequency to see whether reflected-wave voltage calls for an output filter.
This lead length is entering the reflected-wave zone. Use an inverter-duty motor or add a dV/dt filter at the drive output to protect the windings.
These are conservative field rules. The drive manufacturer published cable-length table for your specific drive and filter always takes precedence.
Motor Nameplate Decoder
Enter the nameplate data to decode FLC for circuit sizing, poles and slip, design letter, insulation class and overload setting.
This is a 10 hp, 460V motor. NEC Table 430.250 full-load current for circuit sizing is about 14.0 A. Approximately 4 poles, 1800 RPM synchronous, about 2.8% slip. Design B: normal starting torque, normal starting current. The most common general-purpose design. Class F insulation allows about 155 C total. Service factor 1.15 means the overload should be set near 16.3 A (125% of nameplate FLA).
Power Factor and Capacitor kVAR Helper
Enter the load and the present and target power factor to size the capacitor kVAR needed, with an over-correction check.
Adding this capacitor kVAR raises the power factor to the target without over-correcting. This reduces demand charges and frees up transformer and conductor capacity.
Enter the motor no-load kVAR to enable the over-correction check. Leave it at zero to size for a panel-level capacitor bank.
Instrumentation
RTD and thermocouple temperature, 4 to 20 mA loop burden, and transmitter range scaling.
RTD and Thermocouple Reader
Pick the sensor and enter resistance or millivolts to convert to temperature, with the IEC 60751 tolerance for RTDs.
For a PT100 (R0 100 ohm), this resistance reads about 25.7 C. IEC 60751 tolerance is about plus or minus 0.20 C for Class A and plus or minus 0.43 C for Class B at this temperature.
Loop Power and Burden Checker
Enter the supply, transmitter minimum and loop resistances to check that a 4 to 20 mA loop can drive full scale.
The supply can drive the loop with margin to spare at 20 mA. The transmitter will hold the signal across the full range.
NAMUR NE43: a healthy signal sits between 3.8 and 20.5 mA. Below 3.6 mA flags a fault or under-range, above 21 mA flags over-range, and about 2 mA points to a broken wire.
Transmitter Range Scaler
Convert between 4 to 20 mA and engineering units, in linear or square-root flow mode, against your range.
12.00 mA maps to about 50.00 engineering units on this linear range.
Compressor Controls
Diagnose trips, pick the right control mode, and match air quality to ISO 8573-1.
Compressor Trip Diagnoser
Pick the symptom and get the most likely causes plus a field check list, with a safety note for electrical work.
- 1.Check oil level and quality, top up or change if old or dark
- 2.Inspect cooler fins and clean any blockage, confirm the fan is running
- 3.Verify room ambient is within the spec on the data plate
- 4.Test the thermostatic mixing valve and coolant flow
Most likely low or degraded oil, a clogged or dirty cooler, high ambient temperature, a failed thermostatic valve, or low coolant flow.
Compressor Control Mode Selector
Describe the load profile and storage to get the recommended control mode and why it fits.
Variable speed control matches motor speed to demand. It gives the best part-load efficiency and the smoothest header pressure for variable demand.
Variable speed drive control tracks a changing demand closely and gives the best part-load efficiency, typically 20% to 35% better than modulation at part load.
Air Quality Class Picker
Pick the application and the lowest line temperature to get the required ISO 8573-1 class and dryer type.
General shop air and pneumatic tools run well on a refrigerated dryer at about +3 C pressure dew point.
The dryer pressure dew point stays below the coldest line temperature, so the air will not condense in service. The selected ISO 8573-1 class fits the application.
CNC / FANUC
Tapping feed for G84, peck drill cycle selection, and work offset and tool comp decoding.
Tapping Feed (G84)
Enter the spindle speed and thread to get the synchronized tapping feed and a ready G84 line for FANUC rigid tapping.
M29 S500 (rigid) then G84 Z-.5 R.1 F25.00 S500
At 500 RPM the synchronized tapping feed is about 25.00 in/min. On a FANUC control, command rigid tapping with M29 S500 on the line before the G84 cycle so the spindle and feed stay locked together.
Peck Drill Cycle Helper
Enter the hole depth and drill diameter to get the right drilling cycle, speed, feed and a sample G code line.
G73 Z-1.000 R.1 Q0.250 F6.72 S1222
At a depth to diameter ratio of about 4.0 times, use G73, high-speed peck (short retract, chip break). Set the peck increment Q near 0.250 in and keep the R plane about 0.1 in above the surface.
Work Offset and Tool Comp Decoder
Pick a fixture or compensation code to get a plain-English meaning and the one thing to watch out for.
Work coordinate system 1. Shifts program zero to the stored G54 fixture offset. This is the most common first setup origin.
Confirm the part zero in the G54 register matches where you touched off, a wrong offset crashes into the fixture.
Work coordinate system 1. Shifts program zero to the stored G54 fixture offset. This is the most common first setup origin.
