9.2 Commissioning the AC Drive
Follow these instructions to commission the AC drive.
Read the safety instructions in 2.2 Danger and Warnings and 9.1 Safety Checks before Starting the Commissioning and obey them.
Procedure
Make sure that the motor is installed correctly.
Make sure that the motor is not connected to mains.
Make sure that the AC drive and the motor are grounded.
Make sure to select the mains cable, the brake cable, and the motor cable correctly.
For information on cable selections, see:
6.1.3 Cable Selection and Dimensioning and related tables
6.1 Cable Connections
6.2 EMC-compliant Installation
Make sure that the control cables are sufficiently far from the power cables. See 6.5.1 Additional Instructions for Cable In-
stallation
Make sure that the shields of the shielded cables are connected to a grounding terminal that is identified with the ground-
ing symbol.
Do a check of the tightening torques of all the terminals.
Make sure that no power correction capacitors are connected to the motor cable.
Make sure that the cables do not touch the electrical components of the drive.
Make sure that the common input +24 V is connected to an external power source and the ground of the digital input is
connected to ground of the control terminal.
Do a check of the quality and quantity of the cooling air.
For further information on cooling requirements, see:
5.2.1 General Cooling Requirements
5.2.2 Cooling of FR4 to FR9
5.2.3 Cooling of Standalone AC drives (FR10 to FR11)
12.8 VACON® NXP Technical Data
Make sure that there is no condensation on the surfaces of the AC drive.
Make sure that there are no unwanted objects in the installation space.
Before connecting the drive to mains, do a check of the installation and the condition of all the fuses (see
12.3.1 List of
Cable and Fuse Size Information ) and other protective devices.
9.3 Measuring the Cable and Motor Insulation
Do these checks if necessary.
NOTE! AC drive is already measured at the factory.
The insulation checks of the motor cable, see 9.3.1 Insulation Checks of the Motor Cable
The insulation checks of the mains cable, see 9.3.2 Insulation Checks of the Mains Cable
The insulation checks of the motor, see 9.3.3 Insulation Checks of the Motor
9.3.1 Insulation Checks of the Motor Cable
Use these instructions to check the insulation of the motor cable.
Procedure
Disconnect the motor cable from the terminals U, V, and W and from the motor.
Measure the insulation resistance of the motor cable between phase conductors 1 and 2, between phase conductors 1 and
3, and between phase conductors 2 and 3.
Measure the insulation resistance between each phase conductor and the grounding conductor.
The insulation resistance must be >1 MΩ at the ambient temperature of 20 °C (68 °F).
