Installation Safety Requirements
Aries drives meet the requirements of both the European LVD (Low Voltage
Directive) and EMC (Electromagnetic Compliance) directives when installed
according to the instructions given within “Appendix C Regulatory
Compliance–UL and CE”.
As a rule, it is recommended that you install the drive in an enclosure to
protect it from atmospheric contaminants and to prevent operator access
while power is applied. Metal equipment cabinets are ideally suited for
housing the equipment because they provide operator protection, EMC
screening, and can be fitted with interlocks arranged to remove all hazardous
motor and drive power when the cabinet door is opened.
Do not arrange the interlocks to open circuit the motor phase connections
while the system is still powered as this could damage the drive.
Precautions
During installation, take the normal precautions against damage caused by
electrostatic discharges.
• Wear earth wrist straps.
• Include a mains power switch or circuit breaker within easy reach of
the machine operator. Label, clearly, the switch or breaker as the
disconnecting device.
Auto-Configuration for Encoders
The Aries drive recognizes “smart encoders” attached to Parker motors. You
can apply power to the drive, and the drive reads all necessary motor
parameters from the motor. The drive and motor are then ready to use.
If a drive is swapped out for any reason, you can insert a replacement—the
replacement drive automatically reads the motor parameters.
Several drive related parameters may need additional configuration: CMDDIR,
DCMDZ, and ADDR.
