Torque Curve
Type of torque curve used by the VSM500 unit. A variable torque curve
provides a squared V/Hz curve, 110% electronic thermal overload, and
110% current limit for one minute. A constant torque curve provides a linear
V/Hz curve, 150% electronic thermal overload, and 150% current limit for
one minute.

IR Compensation
Compensation for the voltage drop across the stator resistance in an
induction motor. A voltage is added to the commanded output voltage
based on the load current. The default value of 100% is the factory
determined optimum for the drive. It can be adjusted higher or lower to suit
the needs of the application. A setting of 0% disables this function.

Slip Compensation
Compensation for the inherent slip in an induction motor. A frequency is
added to the commanded output frequency based on load current. The
default value of 100% is the factory determined optimum for the drive. It
can be adjusted higher or lower to suit the needs of the application. A
setting of 0% disables this function.

Analog Minimum
The percent of analog input used to represent parameter 30 [
MINIMUM
FREQUENCY
]. If the minimum analog input equals minimum frequency, no
action is needed. If it is desired to adjust the analog input to equal
parameter 30 [
MINIMUM
FREQUENCY
], use parameter 08 -[
ANALOG
INPUT
] to
adjust the analog input to the desired level and then enter the value in
parameter 48.

The parameter can be set only when the drive is stopped.
3
The parameter can be set only then the VSM500 Integrated drive/motor does not have an active I/O connection.
