*1.
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.
2
•
SGD7S-3R8A to -780A and SGD7W-5R5A to -7R6A (external dynamic brake resistor): Pn001 = n.
0
*2.
If an external dynamic brake resistor is not connected, the Servomotor will coast to a stop.
Note: 1. 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.
2. The setting of Pn00A is ignored if Pn001 is set to n.
0
or n.
1
.
3. The setting of Pn00A = n.
X is enabled for position control and speed control. During torque control,
the setting of Pn00A = n.
X will be ignored and only the setting of Pn001 = n.
X will be used.
4. For more information on Pn406 (Emergency Stop Torque), refer to the standard SERVOPACK product
manual.
5. For more information on Pn30A (Deceleration Time for Servo OFF and Forced Stops), refer to the standard
SERVOPACK product manual.
