Motor Switch Delay Time

Factory Setting: 1.0

Settings 0.0~3600.0 sec Unit: 0.1

 This parameter determines time interval of two motors during circulative control (11-01=01). Users

need to set suitable time delay to avoid water hammer effect damaging AC drive, motor or system.

 This parameter determines time interval between power supply changes from AC drive to

commercial power during fixed circulative control (11-01=02). Users need to set the suitable time

delay to make no shock to motor and runs by commercial power.

Motor Switch Delay Time during Fixed Amount

Circulation

Factory Setting: 10.0

Settings 0.0~3600.0 sec Unit: 0.1

 This parameter determines time interval between motor switch frequency and power supply of motor

is not from AC drive during fixed amount circulation (11-01=02)/fixed amount control (11-01=03)

and output frequency of AC drive attained.

 As the diagram shown below, after output frequency attains 11-06 motor switch frequency, motor

doesn’t switch at once. It will do motor switch action of circulation control after waiting the delay

time that is set by 11-05. Suitable delay time setting will decrease motor switch times.

 After power supply of motor is not from AC drive, the motor will coast to stop according to loading

characteristics. Users need to set 11-06 motor switch frequency and 11-04 delay time of circulation

control according to actual situation to make rotor speed equals to commercial frequency.
