Parameterize power input
To ensure correct parameterization of the power input, edit the following
parameters:
•
A35 low voltage limit
: Specify in this parameter the minimum voltage that
must be applied in the DC link during operation.
•
A36 mains voltage
: connected to X10, effective supply voltage.
•
A38 DC power-input
: Leave the default setting
0:inactive
if the drive
controller will be fed with power via the supply voltage connected to
terminal X10. If the drive controller will be supplied with power exclusively
via the DC link, set the parameter to
1:active
.
Lower limit value for the voltage in the DC link.
If the DC link voltage is less than the set value while the drive controller is
enabled, event
46:low voltage
with cause
1:low Voltage
is triggered.
Connected to X10, effective supply voltage.
The charge relay is controlled to ensure low wear depending on the current DC
link voltage and
A36
.
In control mode
B20 = 64: SSM - vector control
affects
A36
the field weakening
mode. A limit value is derived from
A36
. DC link voltages above this limit value
are not taken into consideration in field weakening mode to prevent oscillations
in the motor current.
In this parameter you can adjust whether the drive controller will be supplied
exclusively with DC voltage via the DC link.
Information
Note that to ensure correct functionality of the DC link, parameter
A38 DC power-input
must be set to:
Group 1:

=
0:inactive
