Example: Start the motor at a specified speed

Proceed as follows to get the connected motor to turn at a speed of 500 rpm:

1. Enter the value "500" in the mySetpoint variable.

2. Set the myCommand variable to CMD_START in the symbol browser.

3. Start the command with myCmdExecute = TRUE.

The input parameter myFC_Control_In.setpoint is set to the speed parameterized in the

mySetpoint variable accordingly and transferred to the input parameter setpoint.

All enables in control word 1 are set. The motor starts to turn.

After the speed parameterized in the mySetpoint variable is reached, the command is ended

with myCmdDone = TRUE.

Note

When starting the motor with a rising edge on bit 0 in STW 1, bit 8 and bit 9 in STW 1 (jog

right/left) must have the signal level FALSE.

Assignment of ctrlDword (STW 1 and STW 2 of ET 200S FC) when starting the motor:

CMD_START

CMD_JOG_RIGHT : // motor jog. Right

CMD_JOG_LEFT

Example: Stop a running motor

Proceed as follows to stop a running motor:

1. Set the myCommand variable to CMD_STOP in the symbol browser.

2. Start the command with myCmdExecute = TRUE.

Bit 0 in control word 1 (On/Off) is reset. The motor begins to stop.

After reaching the actual speed < 1 rpm, the command is terminated with

myCmdDone = TRUE.

Note

Bit 0, bit 8, and bit 9 in STW 1 must have the signal level FALSE when stopping a motor.

Assignment of ctrlDword (STW 1 and STW 2 of ET 200S FC) when stopping the motor:

CMD_STOP
