4. OPERATION AND DISPLAY
4.1 When switching power on for the first time
Before starting operation, check the following:
(1) Wiring
(a) A correct power supply is connected to the power input terminals (P24M, P24G, P24L) of the servo
amplifier.
(b) The servo motor power supply terminals (U, V, W) of the servo amplifier match in phase with the
power input terminals (U, V, W) of the servo motor.
(c) The servo motor power supply terminals (U, V, W) of the servo amplifier are not shorted to the
power input terminals (P24M, P24G, P24L) of the servo motor.
(d) The servo amplifier is grounded securely.
(e) 24VDC or higher voltages are not applied to the pins of connectors CN1A and CN1B.
(f) SD and LG of connectors CN1A and CN1B are not shorted.
(g) The wiring cables are free from excessive force.
(h) CN1A should be connected with the bus cable connected to the servo system controller or preceding
axis servo amplifier, and CN1B should connected with the bus cable connected to the subsequent
axis servo amplifier or with the termination connector (MR-A-TM.)
(2) Axis number
The axis number setting of CS1 should be the same as that of the servo system controller. (Refer to
Section 3.9.)
(3) Parameters
On the servo system controller screen or using the servo configuration software, make sure that
correct values have been set in the parameters.
(4) Environment
Signal cables and power cables are not shorted by wire offcuts, metallic dust or the like.
(5) Machine
(a) The screws in the servo motor installation part and shaft-to-machine connection are tight.
(b) The servo motor and the machine connected with the servo motor can be operated.
