Running; First Power-On - INVT DA180-S2R8SG0 Operation Manual

DA180 series basic AC servo drive

5.1 Running

5.1.1 First power-on

Ensure the following before the power-on:
Wiring

The power supply (L1 and L2) of the servo drive is connected correctly. For details, see
section 3.2 "Main circuit terminal wiring".

The servo drive output phases (U, V, and W) are consistent with servo motor cable
phases.

There is no short circuit between the servo drive outputs (U, V, and W) and the input
power (L1 and L2).

Wiring complies with the standard wiring diagrams for different control modes in chapter 4
"Control modes".

The external servo enabling terminal SON is set to OFF.

The servo drive and the servo motor are grounded properly.

If an external brake resistor is used, for products with small power range, the
short-connection cable between B2 and B3 must be removed.

The voltage applied to CN1 cannot be greater than DC24V.

Stresses applied to cables are within the allowed ranges.
Environment
There are no foreign materials, such as wire leads and metal filings, which can cause short
connection between signal and power cables.
Mechanical parts

The installation of the servo motor and the connection between shafts and machines are
reliable.

The servo motor and connected machines are operational.

Do not run the motor with a negative load, which indicates the motor output torque
direction is opposite to the motor speed direction.
You can turn on the power only after all the preceding conditions are met.
5.1.1.1 Sequence of power-on and power-off
The control circuit and main circuit of the drive are powered together, thus indicating L1 and L2 are
powered together.
