Setup - Preliminary recommendations
Prior to switching on the drive
Prior to configuring the drive
Using the drive with motor having a different size
The motor could have different rating than drive. In case of smaller motor, there is no specific calculation. The motor current has to be set
on Motor thermal current
ItH
parameter page 80. In case of higher size of motor, possible up to 2 sizes (example is using a 4 kW (5.5 HP)
on a 2.2 kW (3 HP) drive) it is necessary to ensure motor current and actual motor power will not pass over nominal power of drive.
Line contactor
Use with a smaller rated motor or without a motor
• In factory settings mode, Output Phase loss
OPL
page 80 is active (
OPL
set to
YES
). To check the drive in a test or maintenance
environment without having to switch to a motor with the same rating as the drive (particularly useful in the case of high power drives),
deactivate Output Phase loss
OPL
(
OPL
set to
nO
).
• Set Motor control type

DANGER
UNINTENDED EQUIPMENT OPERATION
Ensure that all logic inputs are inactive to help prevent an accidental startup.
Failure to follow these instructions will result in death or serious injury.
DANGER
UNINTENDED EQUIPMENT OPERATION
• Read and understand this manual before installing or operating the ER12 drive.
• Any changes made to the parameter settings must be performed by qualified personnel.
• Ensure that all logic inputs are inactive to help prevent an accidental startup when modifying parameters.
Failure to follow these instructions will result in death or serious injury.
CAUTION
RISK OF DAMAGE TO THE DRIVE
• Avoid operating the contactor frequently to avoid premature aging of the filter capacitors.
• Power cycling must be MORE than 60 seconds.
Failure to follow these instructions can result in equipment damage.
CAUTION
RISK OF DAMAGE TO THE MOTOR
Motor thermal protection will not be provided by the drive if the motor rating current is less than 20% of the rated drive current. Provide
an alternative means of thermal protection.
Failure to follow these instructions can result in equipment damage.
