STARTUP
• When you use a linear servo motor, replace the following left words to the right words. Load to motor inertia
ratio
Load to motor mass ratio Torque
Thrust
• Setting [Pr. PN02 Communication error detection time] to a few milliseconds may trigger [AL. 86.1] when the
power of the servo amplifier is cycled or an instantaneous power failure occurs during CC-Link IE Field
Network Basic communication.
• Setting [Pr. PN10 Ethernet communication time-out selection] to a few milliseconds may trigger [AL. 86.4]
when the power of the servo amplifier is cycled or an instantaneous power failure occurs during SLMP
communication.
• CC-Link IE Field Network Basic cannot be used with CC-Link IE Field Network. In wiring, isolate these
networks with a gateway or other means.
The items shown in the following table are the same as those for the motion mode. For details, refer to the section indicated in
the detailed explanation field. "MR-J4-_GF_" means "MR-J4-_GF_(-RJ) Servo Amplifier Instruction Manual (Motion Mode)".
WARNING
• When executing a test run, follow the notice and procedures in this instruction manual. Otherwise, it may cause a malfunction, damage to the machine, or
injury.
• Do not operate the switches with wet hands. Otherwise, it may cause an electric shock.
CAUTION
• Before starting operation, check the parameters. Improper settings may cause some machines to operate unexpectedly.
• The servo amplifier heat sink, regenerative resistor, servo motor, etc., may be hot while the power is on and for some time after power-off. Take safety
measures such as providing covers to avoid accidentally touching them by hands and parts such as cables.
• During operation, never touch the rotor of the servo motor. Otherwise, it may cause injury.
• Before wiring, switch operation, etc., eliminate static electricity. Otherwise, it may cause a malfunction.
