Firmware block:
LIMITS
(20)
Adjusts the drive speed, current and
torque limits, selects the source for
the positive/negative speed reference
enable command and enables the
thermal current limitation.
20.01
MAXIMUM SPEED
(see above).
Defines the allowed maximum speed. See also parameter
0…30000 rpm
Allowed maximum speed.
20.02
MINIMUM SPEED
(see above).
Defines the allowed minimum speed. See also parameter
.
-30000…0 rpm
Allowed minimum speed.
20.03
POS SPEED ENA
(see above).
Selects the source of the positive speed reference enable command.
1 = Positive speed reference is enabled.
0 = Positive speed reference is interpreted as zero speed reference (In the figure below 3.03
SPEEDREF RAMP IN is set to zero after the positive speed enable signal has cleared). Actions in
different control modes:
Speed control: Speed reference is set to zero and the motor is stopped along the currently active
deceleration ramp.
Torque control: Torque limit is set to zero and the rush controller stops the motor.
Example:
The motor is rotating in the forward direction. To stop the motor, the positive speed enable
signal is deactivated by a hardware limit switch (e.g. via digital input). If the positive speed enable
signal remains deactivated and the negative speed enable signal is active, only reverse rotation of the
motor is allowed.
