Tripping condi-
tions for fault 84
Fault 84 "Overtemperature Motor" 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.
Special function 6
MOVIMOT
®
with maximum 8 kHz PWM frequency
Function descrip-
tion
•
The special function reduces the maximum adjustable PWM frequency via S1/7 from
16 kHz to 8 kHz.
•
When DIP switch S1/7 = "ON", the unit operates with an 8 kHz PWM frequency (low
noise) and switches back to 4 kHz depending on the heat sink temperature.
