Chapter 6 - Parameter Description [EXT]
6-58
[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]
F
M 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
[LM Output (LM-CM terminal)]
EXT-40: AM1 (Analog Meter 1) Output – Sub-C
EXT-41: AM1 Adjustment
EXT-42: AM2 (Analog Meter 2) Output – Sub-C
EXT-43: AM2 Adjustment
These terminals are provided on Sub-C board.
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,
