Display Explanation
...%
OVLD%
Status of the electronic motor overload protection as a percentage.
SCR % (silicon-controlled rectifier, power semiconductor temperature rise)
...%
SCR %
Status of the intrinsic device protection as a percentage. This measured value reflects the
temperature rise of the power semiconductor. It comprises the measurement of the heat sink
temperature and the calculated temperature rise of the junction (thermal model of the sem‐
iconductor).
S-TRQ (Soft Torque)
ON
S-TRQ
The function SOFT TORQUE is activated.
OFF
S-TRQ
The function SOFT TORQUE is deactivated.
CNTRL (CONTROL)
LOCL
CNTRL
Manual mode The master control function is with the 3RW5 HMI Standard ("Man‐
ual operation local - HMI controlled" mode).
REMT
CNTRL
Automatic Master control function is not with the 3RW5 HMI Standard. To
make the unit the master control, press the LOCL/REMT key. Refer to
chapter Operating modes and master control function (Page 22).
