11.6.21.3 Error 20-3 (emergency code 8612h)
Cause: Negative hardware limit switch (LSW_N) detected
Suggested steps:
Check your hardware
Position was limited
internally.
l
Please check factor group setting and position
command
l
Take a scope record to determine if the
position control overshoots.
There is a problem with the
digital/analog inputs
l
Please check the 24V I/O wiring, function
assignment and inversion parameters.
l
Please check connected switches for
chattering. Consider using the input filter.
The speed control might run
away, most likely due to a
wrong encoder offset.
l
Please check that the encoder offset is set
properly.
l
If auto commutation is used, re-view the auto
commutation setting and test under all
possible conditions.
l
If torque mode is used, reduce torque, ensure
external speed limitation, or increase speed
control gain for stronger limitation.
11.6.22 Error 21: Initialization, common error
Group error initialization
l
This is a common error number used for
several initialization errors, which have no own
error number

11.6.22.1 Error 21-2 (emergency code 7305h)
Cause: Electronic nameplate, interface, group error: no further information available.
Suggested steps:
Function "Electronic nameplate" not available. Please contact your service provider.
ENP
l
The "Electronic Nameplate" (ENP) is located in
the OEM memory of the motor encoder and
contains primarily motor related data.
l
In the simplest case, the ENP contains only the
commutation angle (ECOFF) between motor
phases and encoder mounting.
11.6.22.2 Error 21-3 (emergency code 7305h)
Cause: Electronic nameplate, parameterization: ENP operation is switched off.
Suggested steps:
Function "Electronic nameplate" not available. Please contact your service provider.
