3.3. Setting of operating parameters
The operating parameters must be adjusted according to the
specific application requirements. Operating parameters can be
modified ON-LINE during operation. However, a preadjustment of
the operating parameters before start-up of the motor is
recommended.
•
C022 Maximum current I
max
Factory set to the maximum controller current. An adjustment
of the maximum current limitation is only necessary if the maxi-
mum current must be smaller than the controller peak current.
•
C011 Maximum speed n
max
In the case of analog set value provision, the maximum motor
speed determines the motor speed at maximum set value. In
the case of digital set value provision, n
max
limits the motor
speed. If n
set
> n
max
the speed is limited to n
max.

directions, CW and CCW).

The acceleration and deceleration times refer to a speed
change from 0 to n

When moving large inertias with short deceleration times, it is
possible that the brake energy would not be dissipated by the
internal brake resistor. The axis module trips and the fault OUE
"overvoltage" or OH1 "overtemperature supply module" is
displayed. In this case it is necessary to increase the
deceleration time or to connect an external brake resistor.
•
C105 Quick stop deceleration time TQSP
The quick stop deceleration time is activated by the function
QSP quick stop.
•
C039 JOG speed
An internally stored speed set value can be activated via X5
terminal 24 or via C045. The JOG speed is set under C039.
