Analog output signals from the S0, S1 terminals can be
used to monitor/display the drive Output Frequency,
Current, Voltage, DC link voltage, External PID and/or
Power (Watts). The output voltage range is 0V to 10V.
Parameters I/O-71, 73 are used to adjust the S0, S1
output gain value.
[Frequency]
The S0/S1 terminal provides an analog output
corresponding to output frequency. The output value is
determined by the following formula:
S0/S1 Output Voltage = (Output freq. / Max. freq.) ×
10V × (IO-71 or 73) / 100.
[Current]
The S0/S1 terminal provides an analog output
corresponding to current. The output value is
determined by the following formula:
S0/S1 Output Voltage = (Output current / Rated
current) × 10V × (IO-71 or 73) / 100.
[Voltage]
The S0/S1 terminal provides an analog output
corresponding to the drives output voltage. The output
value is determined by the following formula:
S0/S1 Output Voltage = (Output voltage / Max. output
voltage) × 10V × (IO-71 or 73) / 100.
[DC link vtg]
The S0/S1 terminal provides an analog output
corresponding to the dc link voltage. The output value
is determined by the following formula:
S0/S1 Output Voltage = (DC link voltage/Max. DC
link voltage) × 10V × (IO-71 or 73) / 100.
Note: Maximum DC Link Voltage for 230V class is
410V and for 460V class 820V.
[Ext.PID Out]
The S0/S1 terminal provides an analog output
corresponding to the External PID output. The output
value is determined by,
S0/S1 output voltage = (External PID output/10000) x
10V x S0, S1 output gain (I/O-71 or 73) / 100.

[Watts]
The S0/S1 terminal provides an analog output
corresponding to output power. The output value is
determined by the following formula:
S0/S1 Output Voltage = (Output Power / 200% Drive
Rating) × 10V × (IO-71 or 73) / 100.
Note: Power calculation is effective power, √3 x V x I.
Note: Output voltage of 10V is based on 200% drive
rated power.
