CHAPTER 2: INSTALL ATION/CONFIGURATION
EPOS MOTOR MANAGEMENT SYSTEM- INSTRUCTION MANUAL

Configuration 6 operation - torque switch activated and switch OFF at torque switch:
In order to start the motor on either direction, the Torque switch 1 reached and torque switch 2 reached inputs (inputs
14 and 15 on EntelliPro ES5) must NOT be active at the same time. .
NOTE:
if both torque switches inputs are active (inputs 14 and 15 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
torque switch 1 is reached (input 14 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 2 is reached (input 15 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.
NOTE:
If “allow direction switchover” is disabled an OFF command is required prior to switching direction.
When an OFF command is received, EntelliPro contact output relays 41 or 43 open, contactors K1 and K2 open, and the
motor stops. The starter logic is fully symmetrical between right and left.
If the default configuration and the actuator 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 0x0,the inputs
and outputs are mapped as below:
