(% U)
1 Initial Torque
Value:
30% - 75% Initial Torque
✭ 75%
Function:
Determines the start torque generated by the motor
when the start command is first applied.
Description of choice:
Set so that the motor begins to rotate as soon as the
start command is given.
2Ramp Up
Value:
2 - 20 seconds, Full Voltage
✭ 10 seconds
Function:
Determines the time taken for voltage to be ramped up
to line voltage.
Description of choice:
Set to optimise motor acceleration and/or start
current. Short ramp times result in quicker acceleration
and higher start currents. Long ramp times result in
slower acceleration and lower start current.
3Ramp Down
Value:
2 - 20 seconds, No Soft Stop
✭ No Soft Stop
Function:
Sets the time of the soft stop voltage ramp. The soft
stop function extends motor deceleration time by
ramping down voltage supplied to the motor when a
stop is initiated.
