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 : // start motor
16#0000 047F hex or binary:
0000 0100 0111 1111
CMD_JOG_RIGHT : // motor jog. Right
16#0000 057E hex or binary:
0000 0101 0111 1110
CMD_JOG_LEFT : // motor jog. Left
16#0000 067E hex or binary:
0000 0110 0111 1110
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 : // stop motor
16#0000 047E hex or binary:
0000 0100 0111 1110
