measurement
Enable 0: Disable
1: Enable
- 1
This parameter enables (1) or
disables (0) the motor stator
resistance measurement when
the drive run signal is given.
Since an auto-tune is usually
carried out during the
commissioning process, the
motor is cold. Temperature
dependent parameters (i.e. stator
resistance) can vary significantly
during operation.
Whenever the drive is enabled
from a stopped condition,
the drive will start from the
Auto-tuned (cold) parameters.
To adjust for variance in stator
resistance, the drive can perform
a measurement on enable.
A delay of one magnetization time
constant (typically 100 – 200 ms)
can be added before start up. This
function is only active when the
drive is in vector control mode.

Over Voltage
Current Limit
0 to 100% of
motor rated
current
% 0
This parameter is only valid in
vector speed control mode. This
parameter will come into function
once the drive DC bus voltage
increase over certain limit. This
voltage limit is set internally just
below the over voltage trip level.
This parameter will effectively
limit the output torque current
in order to prevent large current
going back to the drive, which
may cause over voltage trip.
A small value in this parameter
will limit the motor control torque
once drive DC bus over this
control level. A higher value may
cause big distortion on the motor
current, which may cause an
aggressive behavior of the motor.
