* Range for collector-ring motors.
** Range for brushless motors.
1. The access password must be written correctly before any setpoints can be written via Modbus. The password is initially the same as the default password,
9
but the two passwords are stored separately, so the keyboard can not be used to change the communications password and vice-versa.
2. The allowable range of FLA is as follows: the minimum full load amps value is 2/5 times the CT ratio; the maximum is equal to the CT ratio.
3. The locked rotor current is range dependent on the FLA setpoint: the minimum is twice the full load amps and the maximum value is 12 times the FLA.
4. REGULATOR OUTPUT must be greater than or equal to FLOOR VOLTS, likewise FLOOR VOLTS must be less than or equal to REGULATOR OUTPUT.
