5.1.1 Pre-operation Checks
To ensure that the motor will operate safely and properly, check and confirm the following items beforehand. If you find
any problems, please deal with them properly before operation.
Table 5-1 Checklist before power-up operation
No.
Elements
1
The power input terminals (L1 and L2) of the servo driver must be properly connected
2
The servo driver output terminals (U, V, W) and the servo motor power cable (U, V, W) must
be in phase and correct.
3
The power input terminals (L1, L2) and output terminals (U, V, W) of the Servo Drive must
not be connected incorrectly.
4
When using the drive's built-in regenerative resistor, the built-in regenerative resistor port
(B2/B3) must be wired correctly.
When using an external regenerative resistor, the external resistor connection port (P+/B2)
must be wired correctly.
5
The DC bus terminals (P+/N) must not be connected backwards.
6
The control signal cable of the servo drive is wired correctly; external signal cables such as
the holding brake and overtravel protection are reliably connected. The power supply to the
brake is correct.
7
The servo driver and servo motor must be reliably grounded.
8
The cable is within the specified limits for wire diameter, force, etc.
9
There are no metal chips, wire heads and other foreign matters inside and outside the servo
driver that will cause short circuit of signal line and power line
10
The external braking resistor is not placed on a combustible object.
11
The mounting of the servo motor, the shaft and the mechanical connection must be reliable.
12
The servo motor and the connected machinery must be in an operable state.
