If the torque command gain is 100%/3V and the input voltage is 9V,
300% torque, the maximum torque of the motor, will be generated.
The motor sometimes revolves in both cases where the controller
didn’t approve a torque command at the offset automatic adjustment
and where the controller approved the torque command with 0V.
This
is because of the voltage offset between the controller and the drive.
Torque Limit
The torque of the servo motor can be limited in either forward or
reverse direction.
There are two methods to limit torque.
The first is internal limit. The internal limit is the limit of the drive itself
by setting parameters regardless of external signals.
The second is external limit. The external limit is determined
according to input signals.
Please set SEt-10 to limit the forward torque
internally. The setting range is 0 to 300% and the
default value is 300.
Please set SEt-11 to limit the reverse torque
internally. The setting range is 0 to 300% and the
default value is 300.
Please set SEt-12 to limit the forward torque
externally. The setting range is 0 to 300% and the
default value is 100.
Please set SEt-13 to limit the reverse torque
externally. The setting range is 0 to 300% and the
default value is 100.
ATTENTION
The maximum allowed voltage of the torque command input
is DC
±
10V.
If the standard voltage fluctuates, the torque command can
also change together. Therefore, a power supply with high
accuracy is needed.
If minute torque adjustment is required, please use a multi-
revolution variable resistor which revolves over 10 times.
If the torque command is bigger than the preset maximum
torque of the motor, an warning for excessive torque
command
(A.08 OtC) will be issued
.
