Compliance With Regulations; Motor; Adjusting Parameters; General Safety Considerations For Remote Operation - Emerson Unidrive M700 User Manual

1.5

Compliance with regulations

The installer is responsible for complying with all relevant regulations, such as national
wiring regulations, accident prevention regulations and electromagnetic compatibility
(EMC) regulations. Particular attention must be given to the cross-sectional areas of
conductors, the selection of fuses or other protection, and protective earth (ground)
connections.
For instructions in achieving compliance with specific EMC standards, please refer to
the relevant drive user guide.
Within the European Union, all machinery in which this product is used, must comply
with the directives stated in the relevant drive user guide.
1.6

Motor

Ensure the motor is installed in accordance with the manufacturer's recommendations.
Ensure the motor shaft is not exposed.
Standard squirrel cage induction motors are designed for single speed operation. If it is
intended to use the capability of the drive to run a motor at speeds above its designed
maximum, it is strongly recommended that the manufacturer is consulted first.
Low speeds may cause the motor to overheat because the cooling fan becomes less
effective. The motor should be installed with a protection thermistor. If necessary, an
electric forced vent fan should be used.
The values of the motor parameters set in the drive affect the protection of the motor.
The default values in the drive should not be relied upon.
It is essential that the correct value is entered in the motor rated current parameter
Pr 00.046, as this affects the thermal protection of the motor.
1.7

Adjusting parameters

Some parameters have a profound effect on the operation of the drive. They must not
be altered without careful consideration of the impact on the controlled system.
Measures must be taken to prevent unwanted changes due to error or tampering
especially if a remote user can access the drive over Ethernet.
1.8

General safety considerations for remote operation

The Ethernet interface enables the possibility of remotely controlling a machine from a
distance. It is vital that when connecting to a machine remotely, adequate safety
procedures are implemented to prevent damage to the machine or injury to personnel.
Any connection to a "live" system has the possibility of altering the state of the machine,
adequate procedures must be implemented to cover this situation.
It is the responsibility of the machine builder to ensure that such a system is safe
and complies with current legislation.
