Safety instructions with regard to commissioning
General safety instructions
In order to prevent injury to persons or damage to material assets
• check before connecting the mains voltage
• the wiring for completeness, short circuit, and earth fault
• the "emergency stop" function of the entire system
• that the motor circuit configuration (star/delta) is adapted to the output voltage of the
controller
• the in-phase connection of the motor
• whether all connectors are locked correctly in order to ensure trouble-free operation.
• whether all connectors of the control terminals and interfaces that are not used are closed
with the supplied plastic caps in order to maintain the certified product features of the safety
system.
• check the setting of the most important drive parameters before enabling the controller:
• the V/f rated frequency must be adapted to the motor circuit configuration!
• the drive parameters relevant for your application must be set correctly!
• the configuration of the I/O terminals must be adapted to the wiring!
• ensure that there are no active speed setpoints before enabling the controller.
• The 8400 protec controllers are provided with a factory set automatic brake operation that
operates the holding brake. If no setpoint is set, the motor is locked by the holding brake.
Safety instructions with regard to motor operation
Danger!
• For thermal reasons, continuous operation of self-ventilated motors at a low field
frequency and rated motor current is not permissible!
• In the Lenze setting, the
Motor temperature monitoring (PTC)
is activated.
• Activate the
Brake resistor monitoring (I2xt)
•
must be used to select 87 Hz operation if a delta-connected asynchronous
motor (nameplate data: 400 V
/230 V
) is to be operated in conjunction with a
drive controller for a mains voltage of 400 V.
