7.6.3 HOLDING TIME FOR DC INJECTION BRAKING C107
The time of the OC injection braking can be set using C107. When setting 999s
under C107, the holding time is not limited. After the holding time, the inverter
switches its output voltage to OV.
To activate the OC brake see 7.3.7.
Caution! Long-term operation of the OC brake may result in overheating the
motor.
7.6.4 AMPLlFICATION
OF MONITOR OUTPUT C108
OFFSET OF MONITOR OUTPUT C109
To adapt analog output signals, e.g. to extern al displays, C108 and C109 are used to
set the amplificationand otfset of the monitoroutput terminal 62.
These settings remain active when the function of the monitor output is changed.
7.6.5 MONITOR SIGNAL C111
The monitor output terminal 62 can be assigned to the signals which are selected
under C111 and can be operated as voltage output (:t 10V) or as current output
(:t 20mA). The function is changed by 52 on the control mode (see 4.3).
The following scaling of the output signals is factory-set:
for frequencies: +fdmax corresponds to VMonitor
-fdmax corresponds to VMonitor
for voltages:
1000 V corresponds to VMonitor
o V corresponds to VMonitor
+ 10V/+20mA
-10V/-20mA
+ 10V/+20mA
+ OV/+OmA
To adapt the display element, otfset and gain can be adjusted. (see 7.6.4).
