9.2.1 Meaning of the bits
The table below informs about the meaning of the individual bits of the status word:
Bit
State
Description
Bit 0
'0'
irrelevant
Bit 1
'0'
irrelevant
Bit 2
'0'
irrelevant
Bit 3
Operating mode: Positioning mode In Position
'1'
Actual position is within the positioning window of the programmed set point.
'0'
Actual position is beyond the positioning window of the programmed set point.
Operating mode: Speed mode: In Position
'1'
Actual rotational speed is within the specified tolerance window of the
target speed.
'0'
Actual speed is outside the specified tolerance window.
Bit 4
Actuator travels:
'1'
Actuator travels.
'0'
Drive stands still (rotational speed <2 rpm).
Bit 5
Operating mode: Positioning mode, upper limit
'1'
Actual position is above the programmed limiting value. Travelling is
possible only in negative direction in inching mode.
'0'
Actual position is below the programmed limiting value.
'0'
Operating mode: Speed mode: irrelevant
Bit 6
Operating mode: Positioning mode, lower limit
'1'
Actual position is below the programmed limiting value. Travelling is
possible only in positive direction in inching mode.
'0'
Actual position is above the programmed limiting value.
'0'
Operating mode: Speed mode: irrelevant
