10.5 Motor Terminal Connections
WARNING
INDUCED VOLTAGE
Induced voltage from output motor cables from different
frequency converters that are run together can charge
equipment capacitors even with the equipment turned
off and locked out. Failure to run output motor cables
separately or use shielded cables could result in death or
serious injury.
•
Run output motor cables separately.
Or
•
Use shielded cables.
•
Simultaneously lock out all the frequency
converters.
•
Comply with local and national electrical codes
for cable sizes. For maximum cable sizes, see
chapter 6.5 Power-dependent Specifications
.
•
Follow motor manufacturer wiring requirements.
•
Do not wire a starting or pole-changing device
(such as Dahlander motor or slip ring
asynchronous motor) between the drive system
and the motor.
10.5.1.1 Motor Cable Configuration
All types of 3-phase asynchronous standard motors can be
used with the drive system.
Factory setting is for clockwise rotation with the drive
system output connected as follows:

Illustration 10.7 Changing Motor Rotation
The direction of rotation can be changed by switching 2
phases in the motor cable, or by changing the setting of
parameter 4-10 Motor Speed Direction
.
Motor rotation check can be performed using
parameter 1-28 Motor Rotation Check
and following the
steps shown in
.

NOTICE
MULTIPLE MOTOR CABLES
If connecting more than 1 set of motor terminals, use
the same number, size, and length of cables for each set
of terminals. For example, do not use 1 cable on one
motor terminal and 2 cables on another motor terminal.
