2.9.4 Detailed description of the status bits
Bit 0
:
target position reached
This bit is set:
- when a transferred target position has been reached successfully (not at the
end of a manual run, elsewise the target position is the same as the
applicable limit switch)
- after manual displacement while at standstill, if readjustment is activated and
the absolute value of the difference of actual and target value is smaller or
equal to the positioning window again
This bit is reset:
- after transferring a target position if the difference from the actual value is
larger than the positioning window (SDO #2006)
- by a manual run
- if an invalid target value has been transferred
- if rotated manually when on standstill
Bit 1
:
drag error
This bit is set:
- if during a run (except in the braking phase) the difference between actual
target position and actual position exceeds the value which has been set with
SDO #2005
This bit is reset:
- with each new run command
Bit 2
:
reverse jog key active
This bit is set:
- if Pin 3 on the key connector is connected with Pin 1 (+24V)
This bit is reset:
- if Pin 3 on the key connector is deconnected from Pin 1 (+24V)
Bit 3
:
forward jog key active
This bit is set:
- if Pin 2 on the key connector is connected with Pin 1 (+24V)
This bit is reset:
- if Pin 2 on the key connector is deconnected from Pin 1 (+24V)
Bit 4:
STO-enabling active
The behaviour of this bit is depending of the acknowledgement bit (bit 14) in the
control word.
a) The acknowledgment bit is not set (low)
STO input status failures are latched, if the positioning system is moving
or a run command is transmitted, otherwise the status of the STO input is
shown.
A latched failure is reset if a new run command is transmitted while the
STO input is active or the acknowledgement bit is toggled
(low
high
low)
“STO-enabling active” is set:
- if the STO input is valid (STO input=high / test pulses present) and no
former failure has been latched
“STO-enabling active” is reset:
- if the STO input is invalid (STO input=low / missing test pulses)
b) The acknowledgment bit is set (high)
The status of the STO input is always shown directly.
“STO-enabling active” is set:
- if the STO input is valid (STO input=high / test pulses present)
“STO-enabling active” is reset:
- if the STO input is invalid (STO input=low / missing test pulses)
