ABB ACSM1 - Pos Ref Lim

Parameters and firmware blocks
250
70
Firmware block:
POS REF LIM
(70)
This block
• selects the sources for the dynamic
limiter inputs
• selects the source for the position
reference enable command
• selects the positioning speed,
acceleration rate and deceleration
limits
• defines the synchron error
supervision window
• shows the limited position
reference and the synchronising
error caused by the dynamic
limitations or position correction
• defines the velocity window for
synchronous velocity supervision.

70.01 POS REF PROFILE FW block: POS REF LIM (see above)
Selects the source for the position reference for the dynamic limiter. Default value is P.4.13, ie, 4.13
POS REF IPO, which is an output of the PROFILE GENERATOR firmware block (see page 242).
Value pointer: Group and index.
70.02 POS REF SYNC FW block: POS REF LIM (see above)
Selects the source for the position reference for the dynamic limiter (added to 70.01 POS REF
PROFILE). Default value is P.4.16, ie, 4.16 SYNC REF GEARED, which is the output of the SYNC
REF MOD firmware block (see page 247).
Value pointer: Group and index.
70.03 POS REF ENA FW block: POS REF LIM (see above)
Selects the source for the position reference enable command. 1 = Enabled. 0 = Disabled, position
reference speed limit is set to zero and any on-going positioning task is interrupted.
Bit pointer: Group, index and bit
70.04 POS SPEED LIM FW block: POS REF LIM (see above)
Limits the positioning reference speed. An active limitation is indicated by 6.09 POS CTRL STATUS,
bit 12.
The unit depends on parameter 60.05 POS UNIT and 60.10 POS SPEED UNIT selections.
0…32768 Position reference speed limit.
