Parameters 127
Automatic
The drive automatically selects the correct
output frequency to start a rotating motor. This
is useful for flying starts: if the motor is already
rotating, the drive will start smoothly at the
current frequency.
Note:
This mode cannot be used in multimotor
systems.
2
Torque boost
The drive pre-magnetizes for 500ms the motor
before the start.
Torque boost is applied at start. Torque boost is
stopped when output frequency exceeds 20 Hz
or when it is equal to the reference value.
Note
: This mode should be selected if a high
break-away torque is required.
Note:
This mode cannot be used to start a
rotating motor.
WARNING!
The drive will start after the set
pre-magnetizing time has passed even if
motor magnetization is not completed. In
applications where a full break-away torque is
essential, ensure that the constant magnetizing
time is long enough to allow generation of full
magnetization and torque.
3
Au
boost
Automatic start with torque boost.
Automatic start is performed first and the motor
is magnetized. If the speed is found to be zero,
torque boost is applied.
4
Defines the start delay. After the conditions for
start have been fulfilled, the drive waits until the
delay has elapsed and then starts the motor.
During the delay, warning
shown.
Note
: Start delay can be used with all start
modes.
