Assignment
Bits 0.7 to 0.4:
Bit
Bit 2: DIR_M
Bit 1: DIR_P
Bit 0: START
Voltage for inching
(0 to 32 511)
Assignment
Bit 2: POS_ DONE
Bit 1: POS_ERR
Bit 0: POS_ACK
Actual value
(linear axis: 0 to 16 777 215; rotary axis: 0 to end of rotary axis - 1)
Cause
The limit switch that lies in the direction in which
the drive is moved is active
Inching: DIR_P and DIR_M = 1
Direction of rotation of the drive and the
encoder varies
Voltage for inching >32 511 or < 0

0 0 0 1
What to Do
Check your switches and the wiring as well as
the DI0 limit switch minus and DI1 limit switch
plus parameters
Check the wiring of the drive and the encoder
as well as the parameter for the reversal of the
direction of rotation and adapting the direction
of the drive.
