Do not work on a drive when a rotating permanent magnet motor is connected to it. A
•
rotating permanent magnet motor energizes the drive including its input power terminals.
Before installation, start-up and maintenance work on the drive:
Stop the motor.
•
Disconnect the motor from the drive with a safety switch or by other means.
•
If you cannot disconnect the motor, make sure that the motor cannot rotate during work.
•
Make sure that no other system can rotate the motor directly or through any mechanical
connection.
Measure that the installation is de-energized.
•
-
Use a multimeter with an impedance of at least 1Mohm.
-
Make sure that the voltage between the drive output terminals (T1/U, T2/V, T3/W) and
the grounding (PE) busbar is close to 0V
-
Make sure that the voltage between the drive input power terminals (L1, L2, L3) and the
grounding (PE) busbar is close to 0V.
-
Make sure that the voltage between the drive DC terminals (UDC+, UDC-) and the
grounding (PE) terminal is close to 0V.
Install temporary grounding as required by the local regulations.
•
Start-up and operation:
Make sure that the motor cannot be run into overspeed, e.g. driven by the load. Motor
•
overspeed causes overvoltage that can damage or destroy the capacitors in the
intermediate circuit of the drive.
General safety in operation
These instructions are for all personnel that operate the drive.
WARNING! Obey these instructions. If you ignore them, injury or death, or damage to the
equipment can occur.
Do not power up the drive more than five times in ten minutes. Too frequent power-ups
•
can damage the charging circuit of the DC capacitors. If you need to start or stop the drive,
use the control panel Hand, Off and Auto keys or commands through the I/O terminals of
the drive.
Give a stop command to the drive before you reset a fault. If you have an external source
•
for the start command and the start is on, the drive will start immediately after the fault
reset, unless you configure the drive for pulse start. See the firmware manual.
Before you activate automatic fault reset functions of the drive control program, make
•
sure that no dangerous situations can occur. These functions reset the drive automatically
and continue operation after a fault.
