When setting limit values always refer to the motor data, the
documentation of the motor manufacturer and the project related
documentation.
Parameter Group 21: Start/Stop/MCB Function
Parameter 21.1 Start Function selects the start mode (for
asynchronous motors only).
Parameters 21.3 – 5 select the process stop mode and the MCB
reaction.
Note! Source of the process stop (if enabled) is selected with parameter
16.1 Process Stop.
Parameters 21.10 – 11 select number and monitoring of MCB feedback
signals. Refer to MCB data for correct setting.
Parameter Group 22: Ramp Functions
Parameter 22.1 Acc/Dec 1 / 2 Sel. selects the acceleration/decelaration
ramp. Typical seting: (ACC/DEC 1)
Parameters 22.2 – 3 determine the ramp times.
It is recommended to set slow ramp times when commissioning is
started and to decrease the values to suit the process requirements
when commissioning proceeds.
Parameter Group 23: Speed Reference
Parameters 23.2 - 3 Inching Speed 1 / 2 dertermine the reference for
the inching speed (applicable for metals applications)
Parameter Group 24: Speed Control
Parameters goup 24 provides all settigs for speed controller tuning.
At this stage of commissioning, it is recommended to decrease the
setting for the gain to 1…2 (24.2 KPS).
Tuning of speed controller is discussed later in this document.
Parameter Group 25: Torque Reference
Torque reference settings are applicable when the drive is in torque
control mode selected with parameter 26.1 Torque Selector.
Parameter Group 30: Motor Fault Functions
Activation and trip reaction of stall protection function is set with
parameter 30.1 Stall Function. Pay special attention to stall protection
parameters 30.2 – 4 so that it does not cause unnecessary trips in such
processes where torque is required at low speeds.
In case of ACS 6000sd, a special SW overload protection function for
the excitation circuit is used. The protection function is tuned with
parameters 30.5 – 9 , see example in Signal and Parameter Table
(SigParACS 6000AD_SD_INU_LXAC...).
Parameter Group 31: Standard Converter Fault Functions
Hint! In case of a multi-drive configuration, cabinet temperature
monitoring must be disabled with parameters 31.2 and 31.4 – 6.
