74 Basic operation – Pro models
Parameters Description - with options or range
Supply Tolerances
Parameters that specifies if Torque control should be used during starting and stopping of the motor and related parameters:
Parameters Description - with options or range
Max Volt Imbalance This parameter is the maximum percentage imbalance that can occur between the lowest and highest
measuring phase voltages before a trip will occur. The parameter can be set between [15% - 25%]. The
default is 20%.
Max Current Imbalance
The current imbalance is monitored while the soft starter in running (and not during Starting and
Stopping). This parameter is the maximum percentage imbalance that can occur between the lowest
and highest measuring phase currents before a trip will occur. The parameter can be set between [5% -
20%]. The default is 10%.
Nominal Grid Voltage This value is factory set to the supply voltage for the model of soft starter and will be between 400V,
525V and 690V.
General Setup
The parameters that can be configured under this group are:
Parameters Description - with options or range
User Language Currently only English is supported for the HMI of the soft starter.
Motor Name This is an alpha numeric string of up to 11 characters that may be used to identify the soft starter
station. Default is “ Motor1 ”.
Local/Remote Mode
This parameter determines if the soft starter is controlled locally (either from the TFT display or a
Modbus master such as the MEsoftstart PC Interface) or remotely via external digital control inputs
(e.g. a physical switch or a PLC).
When ‘Remote operation is selected, the TFT display will not activate the “START MOTOR” button, but
instead will indicate that “REMOTE MODE” is active (with REMCTL in yellow to indicate that the remote
device is in control of the soft starter operation).
Password Edit The default Password is 0 – indicating that no password is active. If a password is required, this password
may be set between 1 – 999999; and then a password will be required for all configuration operations. If
the password is set and then lost, contact your distributor to unlock.
Fault / Incoming CB This parameter configures the relay output on the green terminal X3-6,7 (refer
Figure 26
).
When configured for FAULT relay, this output will be switched whenever a fault occurs
When configured for Incoming CB, the output will be true when power is present at the soft starter.
Communication Setup
General parameters are configured under this group:
Parameters Description - with options or range
RS485 Baudrate
The baud rate on the RS485 port. This parameter is applicable to the MEsoftstart PC Interface as well as
the Modbus RTU interface.
