Restrictions
• If "1: Current feed value" or "2: Real current value" is set in "[Pr.300] Servo input axis type", turn ON the "[Rq.1152] Feed
current value update command (M3212+20n)" to start the speed/position switching control. If the "[Rq.1152] Feed current
value update command (M3212+20n)" turns OFF, minor error (error code: 1BA7H) will occur and the control will not start.
• If "[Pr.300] Servo input axis type" is set to other than "0: Invalid", when the speed control () is started, the minor error
(error code: 1BDFH) will occur and the control will not start.
Units for the servo input axis
The position units and speed units for the servo input axis are shown below for the setting "[Pr.300] Servo input axis type" and
"Unit setting" of fixed parameter.
■Servo input axis position units
Setting value of "[Pr.300]
Servo input axis type"
1: Current feed value
2: Real current value
3: Servo command value
4: Feedback value
■Servo input axis speed units
Setting value of "[Pr.300]
Servo input axis type"
1: Current feed value
2: Real current value
3: Servo command value
4: Feedback value
*1 When Speed control 10multiplier setting for degree axis is valid, this will be the speed unit "10
21474836.47 [degree/min]).
• When "1: Current feed value" or "3: Servo command value" is set in "[Pr.300] Servo input axis type", and the
servo input axis becomes servo OFF by the servo error or forced stop, the amount of value change may be
large. This can be prevented by setting "2: Real current value" or "4: Feedback value" in "[Pr.300] Servo
input axis type".
• When a home position return for the axis where "1: Current feed value" or "2: Real current value" is set in
"[Pr.300] Servo input axis type" is performed, if the servo input axis operation during home position return is
used as the input value, the input is stopped in the midway of home position return. When the servo input
axis operation during home position return is used as the input value, set "3: Servo command value" or "4:
Feedback value" in "[Pr.300] Servo input axis type".
