Manual Operation Mode; Station Jog Operation - Mitsubishi Electric MELSERVO-J4 Instruction Manual

6. HOW TO USE INDEXER
Note 1. When the rest of command travel distance is other than "0", ST1 (Forward rotation start) will not be accepted. Refer to section
6.4.5 (1).
2. RT (Second acceleration/deceleration selection) will not be accepted during operation. Selection of the servo motor speed and
acceleration/deceleration time constants will be enabled by on-edge of ST1 (Forward rotation start). However, when the rest of
command travel distance is other than "0", turning on ST1 (Forward rotation start) will not be enabled.
3. Counting will start when the rest of command travel distance becomes "0".
4. When MEND (Travel completion) is off, the station position outputs will be "0" (all off).

6.3 Manual operation mode

For the machine adjustment, home position adjustment, and others, you can shift the position to any position
with the station JOG operation or JOG operation.

6.3.1 Station JOG operation

(1) Setting
According to the purpose of use, set devices and parameters as shown below. With this operation, DI0
(Next station No. selection 1) to DI7 (Next station No. selection 8) are disabled.

POINT
When the operation mode is changed during operation, inputting ST1 (Forward
rotation start) is disabled until the operation stops. Switch on ST1 (Forward
rotation start) after the operation stops.

The rotation direction to a station No. will be as
follows.
Off: Station No. decreasing direction
On: Station No. increasing direction
Set a servo motor speed.
1. Turning off RT will be as follows.
Acceleration time constant: setting value of [Pr.
PC01 Acceleration time constant 1]
Deceleration time constant: setting value of [Pr.
PC02 Deceleration time constant 1]
2. Turning on RT will be as follows.
Acceleration time constant: setting value of [Pr.
PC30 Acceleration time constant 2]
Deceleration time constant: setting value of [Pr.
