Mitsubishi Electric MELSEC-Q Series - Control in the Control Unit Degree

6 - 9
6 POSITIONING CONTROL
6.1.5 Control in the control unit "degree"
If the control units are "degree", the following items differ from other control units.
(1) Current value address
The current addresses in the control unit "degree" are ring addresses from 0° to
360°.
359.99999 359.99999
000
(2) Stroke limit valid/invalid setting
The upper/lower limit value of the stroke limit in the control unit "degree" is within
the range of 0° to 359.99999°
(a) Stroke limit is valid
Set the "lower limit value to upper limit value of the stroke limit" in a
clockwise direction to validate the stroke limit value.
315.00000

Area A
Area B
1) If the travel range in area A or area B is set, the limit values are as
follows:
Area Lower stroke limit value Upper stroke limit value Remark
Area A 315.00000° 90.00000°
When the feed current value is outside of the stroke limit range,
movement in both the positive and negative direction is possible with
JOG operation or manual pulse generator operation.
Area B 90.00000° 315.00000°
When the feed current value is outside of the stroke limit range,
movement is possible with JOG operation and manual pulse generator
operation in the negative direction if "feed current value > upper stroke
limit value", or in the positive direction if "feed current value < lower
stroke limit value".
(b) Stroke limit is invalid
Set the "upper stroke limit value" equal to "lower stroke limit value" to
invalidate the stroke limit value.
It can be controlled regardless the stroke limit settings.
