Special
function 12
MOVIMOT
®
with rapid start/stop and motor protection via TH
Functional descrip-
tion
•
The special function is active in terminal and bus operation, but there are differences
with respect to the usable functional scope.
•
If the MOVIMOT
®
inverter is mounted close to the motor (with option P2.A or in the
field distributor), the special function consists of the following:
– Motor protection function via indirect TH analysis using direction of rotation termi-
nals
– Rapid start and stop function
"Motor protection
function via TH
analysis" partial
function
This function is active only in bus operation. The special function implements tripping
fault 84 "Excessive motor temperature."
Fault 84 is tripped if all of the following requirements are met:
•
The standard MOVIMOT
®
motor protection function can be deactivated via DIP
switch S1/5 = ON.
•
The direction of rotation terminals are wired to 24 V via a TH as shown in the follow-
ing figure.
•
The TH tripped due to excessive temperature of the motor (release of both direction
of rotation terminals does not apply).
•
Mains voltage is present.
