Application Data; Acceleration And Deceleration; Set Points At Multi-Functional Input - BONFIGLIOLI ACTIVE Cube ACU 201-01 Operating Instructions Manual

8.2.10 Application data

Due to the wide range of drive applications with the resulting parameter settings it is
necessary to check further parameters. The parameters polled during the guided
commissioning procedure were selected from standard applications. After completion
of commissioning, further parameters can be set in the PARA menu branch.
At the control unit KP500 parameter numbers > 999 are displayed hexadecimal at the
leading digit (999, A00 ... B5 ... C66).

8.2.10.1 Acceleration and deceleration

The settings define how fast the output frequency changes after a reference value
change or a start, stop or brake command.
No.
420 Acceleration (clockwise)
421 Deceleration (clockwise)
NOTE
The deceleration of the drive is monitored in the default parameter setting
controller operation mode
of an increase in the DC link voltage during regenerative operation and/or during
the braking process.

8.2.10.2 Set points at multi-functional input

The multi-functional input MFI1 can be parameterized for a reference value signal in

1 - Voltage Input
2 - Current Input
3 - Digital Input
Use multifunction input MFI1 as digital input for slow signals. For rapidly and regularly
changing signals, a digital input S2IND...S6IND or a digital input of an expansion
module EM should be used.
