2 - 2- 1 Pre-operation checks

Before starting operation, check the following:
(1) Wiring
1) A correct power supply is connected to the
power input terminals (L1, L2, L3, L11, L21) of
the servo amplifier.
2) 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.
3) The servo motor power supply terminals (U, V,
W) of the servo amplifier are not shorted to the
power input terminals (L1, L2, L3).
4) The servo amplifier and servo motor are
grounded securely.
5) When the regenerative brake option is used, the
lead has been removed across D-P of the control
circuit terminal block. Also, twisted cables are
used for its wiring.
6) 24VDC or higher voltages are not applied to the
pins of connectors CN3.
7) SD and SG of connectors CN3 are not shorted.
8) The wiring cables are free from excessive force.
9) CN1A should be connected with the bus cable
connected to the 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 3 -
1 -4)
(3) Parameters
On the servo system controller screen or using the set-up 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
1) The screws in the servo motor installation part and shaft-to-machine connection are tight.
2) The servo motor and the machine connected with the servo motor can be operated.
