The following table shows you which activity triggers which result.
Activity Result
Switch the CPU to RUN mode.
• The POS_ACK status bit is deleted
• The POS_ERR status bit is deleted
• The POS_DONE status bit is set
Check the encoder wiring
Check the feedback bit ERR_ENCODER
• If ERR_ENCODER = 1, correct the wiring of the encoder
Inching in the plus direction:
Start inching mode in the plus direction by setting memory
marker 30.0 ("Variable > Modify >")
The status bit POS_ERR = 0, the UP LED lights up
• The POS_ACK status bit is set
• The POS_DONE status bit is deleted
• The actual value is continuously updated
• The POS LED lights up
• The reversal of the direction of rotation you have
parameterized and the wiring of the encoder and drive
are correct
The status bit POS_ERR = 1, the DN LED lights up
Check the assigned parameter reversal of the direction of
rotation and directional adjustment, and the wiring of the
encoder and drive
Check the speed of the drive in the plus direction
Control the speed using memory marker word 32 ("Variable
> Modify >")
• If the drive moves at the correct speed, your wiring is
correct
Inching in the minus direction:
Start inching mode in the minus direction by setting memory
marker 30.1 ("Variable > Modify >" )
The status bit POS_ERR = 0, the DN LED lights up
• The POS_ACK status bit is set
• The POS_ERR status bit is deleted
• The POS_DONE status bit is deleted
• The actual value is continuously updated
• The POS LED lights up
• The reversal of the direction of rotation you have
parameterized and the wiring of the encoder and drive
are correct
The status bit POS_ERR = 1, the UP LED lights up
Check the assigned parameter reversal of the direction of
rotation and directional adjustment, and the wiring of the
encoder and drive
Check the speed of the drive in the minus direction
Control the speed using memory marker word 32
("Variable > Modify >")
• If the drive moves at the correct speed, your wiring is
correct
