If the “soft stop time activated” parameter is set, the by-pass relay 45 will open immediately after the OFF command
is received, and after the soft stop timer expires, output relay 41 opens, K1 opens, and removes power to the soft
starter and motor.
The soft stop timer is set on WinESG parameterization/timer panel and/or Modbus holding register 37
Similarly, when an ON2 command is received, contactor K2, controlled by EntelliPro output relay 43, will close. This
provides power for the soft starter to start and power to drive the motor in the reverse direction. When the soft starter
signals up-to-speed by closing relay UTS, the starter generates the soft starter bypass signal and the EntelliPro ES
relay 45 is then closed.
If bypass control is activated in WinESG parameterization/timer panel or Modbus function code 6 register 111 bit6, an
alarm will be generated when the “soft starter timer” set on WinESG parameterization/timer panel or Modbus
function code 6 register 36 expires prior to the bypass input signal.
When an OFF command is received and the soft stop is activated in WinESG parameterization/timer panel or Modbus
function code 6 register 111 bit5, contactor relay output 45 opens, signaling the soft starter to ramp down.
The opening time of contactor K3, controlled by EntelliPro ES output relay 43, is dependent on the configuration of
“soft stop time activated” parameter set in WinESG parameterization/timer panel or Modbus function code 6 register
111 bit5,
If the “soft stop time activated” parameter is set, the by-pass relay 45 will open immediately after the OFF command
is received, and after the soft stop timer expires, output relay 43 opens, K2 opens, and removes power to the soft
starter and motor.
The soft stop timer is set on WinESG parameterization/timer panel and/or Modbus holding register 37
NOTE:
Ensure soft starter is located before contactor.
If the default configuration and the soft starter reverse typical are selected in the WinESG
parameterization/information shown in the illustration below or by setting Modbus function code 6 register 62 bit0 to
1 and bits 8,9,10 and 11 to 0x5,the inputs and outputs are mapped as below:
