Parameter description

3.2.4 Special Adjustments

The following parameters serve for the optimization of the drive and the adaption to certain applications. These
adjustments can be ignored at the initial start-up.
CP.22 Maximum speed
Co-domain
0...4000 rpm
CP.23 Fixed speed 1 (input 1)
CP.24 Fixed speed 2 (input 2)
Co-domain
CP.23
0...±4000 rpm
CP.24
Input I1 + input I2 = fixed speed 3 (factory setting = 0 rpm)
The Step speed 3 cannot adjusted in the CP-mode.
CP.25 Acceleration time
Co-domain
0.00...300.00 s
∆n Speed change
∆t Acceleration time for ∆n
Setting Description
2100 rpm In order to limit the setpoint value a maximum speed must be preset. This limit
value is the basis for further setpoint calculations and for the determination
of setpoint characteristics. The maximum speed limits the setpoint speed
only. Because of speed ripples, speed overshoot or hardware defects (e.g.
defective encoder) the actual speed may exceed these limits.
Setting Description
Two fixed speeds can be adjusted. The selection is made by the
100 rpm
inputs I1 and I2. If adjustments are made that are outside the fixed
-100 rpm
limit of CP.22, then the speed is internally limited.
Setting Description
5.00 s Defines the time needed to accelerate from 0 to 1000 rpm. The actual
acceleration time is proportional to the speed change (∆n).
Example The drive should accelerate from 300 rpm auf 800 rpm in 1 s.
∆n = 800 rpm - 300 rpm = 500 rpm
∆t = 1 s
