Establishing The Communication; Operating The Servo Motor; Disconnecting The Network - Mitsubishi Electric MELSERVO MR-JET-G-N1 User Manual

Establishing the communication

Start communication with the controller, then confirm that "r" appears on the 7-segment LED display.
Follow the manual for the controller being used when starting communication.
If [AL. 086.1 Network receive data error (Network communication error 1)] occurs, set a threshold in [Pr. PN18 Counter level
for communication error detection] or [Sync Error Counter Limit (Obj. 10F1h: 02h)] that is appropriate for the controller being
used.

Operating the servo motor

An example procedure for operating in cyclic synchronous position mode (csp) is shown below.
Homing mode settings
To operate in cyclic synchronous position mode (csp), first perform homing. Set [Modes of operation (Obj. 6060h)] to "6"
(Homing mode), then confirm that [Modes of operation display (Obj. 6061h)] has changed to "6" (Homing mode). For
information regarding the settings of other control modes, refer to the following section.
Page 38 Control mode
If performing homing via the controller without using homing mode, refer to the following section.
Page 41 Absolute position detection system configuration
Servo-on
Set the control command issued from the controller to [Controlword (Obj. 6040h)], then change the internal state of the servo
amplifier to the "servo-on" state.
For details regarding servo amplifier internal states, refer to the following section.
Page 23 PDS state transitions
Homing
Set the homing method in [Homing method (Obj. 6098h)], then perform homing.
For details regarding homing, refer to "Homing mode (hm) and homing" in the following manual.
MR-JET User's Manual (Function)
Starting servo motor operation
Confirm that homing is complete, then change the control mode to cyclic synchronous mode. Drive the servo motor by giving
commands to [Target position (Obj. 607Ah)], etc. in accordance with the desired operation pattern.

Disconnecting the network

To disconnect the network when stopping the operation of equipment, follow the procedure shown below. Failing to follow the
procedure exactly may cause [AL. 086.1 Network communication error 1].
1.
Stop the servo motor.
2.
Set the Shutdown command for [Controlword (Obj. 6040h)] to establish the servo-off state.
3.
Switch the state to the Pre-Operational state.
4.
Shut off the power of the servo amplifier and the controller.
