Chapter 6 - Parameter Description [EXT]

[Current]

LM terminal outputs inverter output current. The output value is determined by,

LM Output Voltage = (Output current / Rated current) × 10V × EXT-35 / 150

[Voltage]

LM terminal output inverter output voltage. The output value is determined by,

LM Output Voltage = (Output voltage / Max. output voltage) × 10V × EXT-35 / 100

[DC link vtg]

LM terminal outputs the DC link voltage of inverter. The output value is determined by,

LM Output Voltage = (DC link voltage / Max. DC link voltage) × 10V × EXT-35 / 100

[Torque]

FM terminal outputs the motor torque. The output value is determined by,

FM terminal output voltage= (Torque current/Rated torque current)*10V* FM output gain (I/O-41) / 150

Analog meter displays the inverter output Frequency, Current, Voltage and DC link voltage with analog voltage on the AM1 and AM2 terminals of Sub-C board. The output voltage ranges from 0V to 10V. EXT-41 and EXT-43 are used to adjust the AM output value.

[Frequency]

The AM terminal outputs inverter output frequency. The output value is determined by,

AM Output Voltage = (Output freq. / Max. freq.) × 10V

[Current]

The M terminal outputs inverter output current. The output value is determined by,

AM Output Voltage = (Output current / Rated current) × 10V

[Voltage]

The AM terminal outputs inverter output voltage. The output value is determined by,
