2.74 EP OS MOTOR MANAGEMENT SYSTEM – INSTRUCTION MANUAL
Only the following six configurations are valid:
Configuration Limit switch
activated
Torque switch
activated
Switch OFF

Switch OFF at
torque switch Switch OFF
at current threshold
1 Enabled Enabled
2 Enabled Enabled
3 Enabled Enabled Enabled
4 Enabled Enabled Enabled
5 Enabled
6 Enabled Enabled
NOTE: The current threshold level is set in WinESG parameterization/device settings panel as shown in the illustration
below or Modbus function code 6 register 21.
Configuration 1 operation - limit switched activated and switch OFF at limit switch:
In order to start the motor on either direction, the limit switch 1 reached and limit switch 2 reached inputs (inputs 96 and
97on EntelliPro ES3 and inputs 18 and 19 on EntelliPro ES5) must NOT be active at the same time.
NOTE: If both limit switches inputs are active (input 96 and 97 on EntelliPro ES3 and 18 and 19 on EntelliPro ES5) a
“position switch” error will be generated, since this is an invalid condition.
When an ON1 right command is received, contactor K1, controlled by EntelliPro output relay 41, will close, provided the
motor is in the off state and the drawer ready switch is active, which will start the motor in a right direction. When the
limit switch 1 is reached (input 97 on EntelliPro ES3 and input 18 on EntelliPro ES5 active) the motor will stop and will not
rotate in the same direction. The motor can only re-start on the opposite direction by using command ON2, after the
“motor ON direction switchover time” timer set in WinESG parameterization/timer or Modbus function code 6 register 30
expires.
Similarly when an ON2 left command is received, contactor K2, controlled by EntelliPro output relay 43, will close,
provided the motor is in the off state and the drawer ready switch is active, which will start the motor in a left direction. .
When the limit switch 1 is reached (input 96 on EntelliPro ES3 and input 19 on EntelliPro ES5 active) the motor will stop
and will not rotate in the same direction. The motor can only re-start on the opposite direction by using command ON1,
after the “motor ON direction switchover time” timer set in WinESG parameterization/timer or Modbus function code 6
register 30 expires.
In case the motor is running in one direction and a command is received instructing the motor to rotate in opposite
direction, the decision of accepting the commands will be dependent on the configuration of the “allow direction
switchover” parameter set in WinESG parameterization/typical settings panel or the bit set on Modbus function code 6
register 111.
If this bit is set, the motor is allowed to accept the command, which will cause the motor to stop and wait for the
“motor ON direction switchover time” transfer timer to expire before starting the motor in the opposite direction.
