Origin Search Operation
Section 8-2
The speed command value specifies the initial origin search speed until the
origin proximity signal is input. When an origin search is started with the
speed command set to 0 (command units/s), a Speed Designation Error (axis
error code: 3061) will occur and the origin search will not be executed.
Torque limit during operation is possible with origin searches. For further
details on the torque limit function, refer to
10-4 Torque Limits
.
The speed command value, acceleration/deceleration curve designation, and
forward/reverse rotation current limit designation data are enabled when the
ORIGIN SEARCH Bit turns ON.
The SMARTSTEP Junior Servo Drives do not support acceleration/decelera-
tion filters and torque limits. When using a SMARTSTEP Junior Servo Drive,
do not attempt to use an acceleration/deceleration curve designation or for-
ward/reverse torque limit designation.
Note
Do not set both the exponential curve designation and S-curve designation to
1 (enabled) in the acceleration/deceleration curve designation. Enabling both
settings may cause a malfunction.
