Forced drive ON (forced commercial power drive)
• Forced drive ON (forced commercial power drive) is a function to turn on the
relay output forcibly to connect the motor to the commercial power supply. Thus,
even if the run command is off, turn on the relay output to drive the motor by
commercial power.
[ 1 ] Pump control drive motor permission commands 1 to 8 of pump control
motor ("MEN1" to "MEN8")
As mode selection of pump control motors, there are pump control drive motor permission
commands 1 to 8 ("MEN1" to "MEN8") by terminal input. A combination of the pump
control drive motor permission command and the motor mode selection enables motor
degradation. Degradation is a state in which the system is under operation continually with
only the corresponding motor stopped.
