Motor Stopping Method for Overtravel
You can set the stopping method of the Servomotor when overtravel occurs in Pn001 =
n.
XX (Servo OFF or Alarm Group 1 Stopping Method and Overtravel Stopping Method).
The default settings are different for different SERVOPACK models.
•
SGD7S-R70A to -2R8A, SGD7S-R70F to -2R8F, and SGD7W-1R6A to -2R8A (no dynamic
brake): Pn001 = n.
02
•
SGD7S-3R8A to -780A and SGD7W-5R5A to -7R6A (external dynamic brake resistor):
Pn001 = n.
00
*1.
You cannot decelerate a Servomotor to a stop during torque control. For torque control, the Servomotor will be
stopped with the dynamic braking or coast to a stop (according to the setting of Pn001 = n.
X (Servo OFF
or Alarm Group 1 Stopping Method)), and then the Servomotor will enter a coasting state.
*2.
The Servomotor will coast to a stop if you use a SERVOPACK that does not support the dynamic brake hard-
ware option specifications (SGD7S-R70A to -2R8A, SGD7S-R70F to -2R8F, or SGD7W-1R6A to -2R8A) or do
not connect an external dynamic brake resistor.
*3.
For detailed information on settings, refer to the standard SERVOPACK product manual.
Note: If Pn001 is set to n.
0 (Stop the motor by applying the dynamic brake) when using an SGD7S-R70A to
-2R8A, SGD7S-R70F to -2R8F, or SGD7W-1R6A to -2R8A, an A.042 (Parameter Combination Error) alarm
will occur.
Refer to the standard SERVOPACK product manual for information on stopping methods other
than those for overtravel.
