can be input also at O2 terminal.
Maximum frequency is attained at DC 20mA in DC 4 - 20mA range.
Frequency Command Terminal
When the intelligent terminal configured as AT is on, OI signal is enabled.
Analog Output Monitor (Voltage)
Selection of one function from:
Output frequency, output current, torque, output voltage, input
power, electronic thermal load ratio, and LAD frequency.
Analog Output Monitor (Current)
[DC0-10V output (PWM output)] Selection of one function from:
