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.
Position, synchron, homing and profile velocity control: Dynamic limiter sets the positioning speed
limit to zero and the motor is stopped according to
.
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 (eg, 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.
Bit pointer: Group, index and bit
20.04
NEG SPEED ENA
(see above)
Selects the source of the negative speed reference enable command. See parameter
.
Bit pointer: Group, index and bit
20.05
MAXIMUM CURRENT
(see above)
Defines the allowed maximum motor current.
0…30000 A
Maximum allowed motor current.
20.06
MAXIMUM TORQUE
(see above)
Defines the maximum torque limit for the drive (in percent of the motor nominal torque).
0…1600%
Maximum torque limit.
20.07
MINIMUM TORQUE
(see above)
Defines the minimum torque limit for the drive (in percent of the motor nominal torque).
-1600…0%
Minimum torque limit.
