Appendix G - Prole Torque Mode (Servo Only)
General Mode Description
Prole Torque mode is a servo-control torque operating mode. It requires knowledge of the
Torque Constant of the motor in Nm/A. This information can be found in the motor print.
Enable Prole Torque Mode
To enable Prole Torque Mode, the value 0004
h
must be written to the mode of operation
OD entry, located at dictionary address 6060
h
.
The mode of operation can be veried using OD 6061
h
- mode of operation display - which
is updated when the current operation mode is accepted.
Set Running Parameters
To operate in Prole Torque mode, the following parameters must be set:
Figure 17: Set Running Parameters
Enable Drive Operation
After power up or node reset, the drive is in disabled state. The value 0006
h
must be
written to the control word OD entry, located at dictionary address 6040
h
. This will put the drive
into “ready to switch on” state and is ready to enable drive operation. If the value 0006
h
is not
written to the control word rst, the drive operation can not be enabled.
To enable drive operation, the value 000F
h
must be written to the controlword OD entry,
located at dictionary address 6040
h
. This puts the drive into the Operation Enabled state with
no torque applied.
It should be noted that both enabling the halt bit and setting the target torque to zero will
ramp down the torque applied to the motor according to the torque slope. At the end of the
slope no torque will be applied to the motor, allowing the shaft to move freely.
