Program features 55
In the ACS880, the following settings are made:
•
•
•
= 2048
•
•
•
, as the received
number of pulses is 4 times nominal. See also parameter
•
The desired “data out” parameter is set to Other –
(32-bit format). Only the high word needs to be specified – the subsequent
data word is reserved for the low word automatically.
•
The desired sources (such as digital inputs or user bits of the control word) are
selected in
and
In the PLC, if the initial value is set in 32-bit format using low and high words
(corresponding to ACS800 parameters POS COUNT INIT LO and POS COUNT INIT
HI), enter the value 66770 into these words as follows:
Eg. PROFIBUS:
•
FBA data out x = POS COUNT INIT HI = 1 (as bit 16 equals 66536)
•
FBA data out (x + 1) = POS COUNT INIT LO = 1234.
ABB Automation using DDCS communication, eg.:
•
Data set 12.1 = POS COUNT INIT HI
•
Data set 12.2 = POS COUNT INIT LO
To test the configuration of the PLC, initialize the position counter with the encoder
connected. The initial value sent from the PLC should immediately be reflected by
in the drive. The same value should then appear in the
PLC after having been read from the drive.

Jogging
The jogging function enables the use of a momentary switch to briefly rotate the
motor. The jogging function is typically used during servicing or commissioning to
control the machinery locally.
Two jogging functions (1 and 2) are available, each with their own activation sources
and references. The signal sources are selected by parameters
. When jogging is activated, the drive starts
and accelerates to the defined jogging speed (
