After the installation:
•
Make sure that the motor is installed correctly.
•
Make sure that the motor terminals are not connected to mains.
•
Make sure that the AC drive and the motor are grounded.
•
Make sure that you select the mains cable, the brake cable, and the motor cable
correctly (see chapter 5.3 Cable dimensioning and selection).
•
Make sure that the control cables are as far as possible from the power cables. See
chapter 5.6 Cable installation.
•
Make sure that the shields of the shielded cables are connected to a grounding terminal
that is identified with .
•
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 inputs of the digital input groups are connected to +24 V or
ground of the control terminal or the external power source.
•
Do a check of the quality and quantity of the cooling air. See chapter 4.6 Cooling and
Table 14 The necessary quantity of cooling air.
•
Make sure that there is no condensation on the inner surfaces of the AC drive.
•
Make sure that there are no unwanted objects in the installation space.
•
Before you connect the drive to mains, do a check of the installation and the condition of
all the fuses and other protective devices.
7.3 OPERATION OF THE MOTOR
7.3.1 CHECKS BEFORE STARTING THE MOTOR
Before you start the motor, do these checks.
•
Make sure that all the START and STOP switches that are connected to the control
terminals are in the STOP position.
•
Make sure that you can start the motor safely.
•
Activate the Start-up wizard. See the Application Manual for the AC drive that you have.
•
Set the maximum frequency reference (that is, the maximum speed of the motor), so
that it agrees with the motor and the device that is connected to the motor.
7.4 MEASURING THE CABLE AND MOTOR INSULATION
Do these checks if necessary.
The insulation checks of the motor cable
1
.
Disconnect the motor cable from the terminals U, V, and W and from the motor.
2
.
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.
3
.
Measure the insulation resistance between each phase conductor and the grounding
conductor.
4
.
The insulation resistance must be >1 MΩ at the ambient temperature of 20 °C (68 °F).
