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.
This manual contains instructions for achieving compliance with specific EMC
standards.
Within the European Union, all machinery in which this product is incorporated must
comply with the following directives:
2006/42/EC: Safety of machinery.
2004/108/EC Electromagnetic Compatibility.
1.11
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. It is
strictly prohibited to use the motor with higher speeds than are deemed maximum.
Low speeds may cause the motor to overheat because the cooling fan becomes less
efficient. The motor should be installed with a protection thermistor. If necessary, an
electric forced vent fan should also 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 Pr
00.046
motor rated current. This
affects the thermal protection of the motor.
1.12
Mechanical brake control
The drive brake control functions are provided to allow well co-ordinated operation of an
external brake with the drive. While both drive hardware and software are designed to
high standards of quality and robustness, they are not intended for use as safety
functions, i.e. where a fault or failure would result in a risk of injury. In any application
where the incorrect operation of the brake release mechanism could result in injury,
independent protection devices of proven integrity must also be incorporated. The
SI-Safety module Safe Brake Control (SBC) output can be connected to a suitable
safety related device to provide a safety function.
1.13
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.
