Programmable fault:
STO DIAGNOSTIC
Cause
Safe Torque Off function is
active, i.e. safety circuit signal 2
connected between X6:2 and
X6:4 is lost while drive is at
stopped state and parameter
46.07 STO DIAGNOSTIC
setting is (2) ALARM
Error in changing Safe Torque
Off supervision, i.e. parameter
46.07 STO DIAGNOSTIC
setting could not be changed to
value (1) FAULT.
Interface board (between power
unit and control unit)
temperature has exceeded
internal fault limit.
Input bridge or brake chopper
temperature has exceeded
internal fault limit.
Autophasing routine (see
section Autophasing
37) failed.
Connection between the JCU
Control Unit and the power unit
of the drive is lost.
Communication errors detected
between the JCU Control Unit
and the power unit of the drive.
Temperature of internal AC
choke excessive.
Fault in external device. (This
information is configured
through one of programmable
digital inputs.)
Safe Torque Off function is
active, i.e. safety circuit
signal(s) connected to
46.07
connector X6 is lost
- during drive start or drive run
or
- while drive is stopped and
parameter 46.07 STO
DIAGNOSTIC setting is
FAULT.
What to do
Check safety circuit connections. For more
information, see appropriate drive hardware
manual.
