Safety Information and Precautions
Certification
CE
i
• The above EMC directives are complied with only when the EMC electric installation requirements
Note
are strictly observed.
• Machines and devices used in combination with this drive must also be CE certified and marked.
The integrator who integrates the drive with the CE mark into other devices has the responsibility
of ensuring compliance with CE standards and verifying that conditions meet European standards.
• The installer of the drive is responsible for complying with all relevant regulations for wiring, circuit
fuse protection, earthing, accident prevention and electromagnetic (EMC regulations). In particular
fault discrimination for preventing fire risk and solid earthing practices must be adhered to for
electrical safety (also for good EMC practice).
• For more information on certification, consult our distributor or sales representative.
AC Motor (Induction/Asynchronous)
AC induction motors are designed to run at fixed speed at the 50 or 60 Hz supply frequency and therefore it's
cooling capability is dependent on the axial driven fan mounted at the non drive end.
When the motor is operated at variable speed with the AC Drive, it is necessary to consider the reduced
cooling rate especially when running at low speed for considerable period of time. Please consult with the
motor manufacturer who can provide cooling solutions such as a electric force ventilated fan or an "AC Drive"
rated AC motor designed to handle reduced speed running with AC Drives.
It is also necessary to consult with the motor manufacturer when above base speed (> 50/60 Hz) running is
required and or when high speed operations are required. Motor suppliers also provide solutions for encoder
feedback devices for close loop operation with an AC Drive.
Adjusting AC Drive Parameters
The AC Drive when it leaves the factory with default settings should enable the user to get started quickly
to check on the basic mechanical running conditions. At a later time, fine tuning to optimize the operation/
performance can be undertaken.
Such parameter tuning should be done by qualified personnel who have prior training on AC Drives. Some
parameter settings if manipulated incorrectly can have adverse reactions and care should be taken especially
during the commissioning startup stages to prevent personnel from engaging the machine.
This manual provides a complete list of the parameters with functional description and care should always be
taken whenever parameters are adjusted during a live running startup. K&R Technology and Authorized
Distributors can provide product training and if in doubt seek advice.
