164 VIX IM MICROSTEPPER INDEXER DRIVE USER GUIDE

SCALE Scale settings
Syntax aSCALEon/off(SCLA,SCLD,SCLV, PEU)
Description This command allows a user to specify Acceleration, Distance and Velocity in
their own chosen units.
The drive firmware needs to know how many commanded position steps
there are in a user unit and then how many fractions of a unit there are for an
A, D or V of 1.
The parameters used are:
SCLA – 1 to 100,000,000 Used to scale A.
A of 1 unit/s2 = PEU encoder counts per sec2. If SCLA <>1, all
acceleration values entered are internally divided by the SCLA
parameter value. Default 1.
SCLD – 1 to 100,000,000 Used to scale D.
D of 1 unit = PEU encoder counts. If SCLD <>1, all distance values
entered are internally divided by the SCLD parameter value. Default
4000.
SCLV – 1 to 100,000,000 Used to scale V.
V of 1 unit/s = PEU encoder counts per sec. If SCLV<>1, all velocity
values entered are internally divided by the SCLV parameter value.
Default 1.
PEU – 1 to 100,000,000 – Position Encoder steps per Unit : defines the
number of position feedback encoder steps in a user unit. The steps referred
to are motor steps if LOADENC is disabled, or load mounted encoder steps if
LOADENC is enabled.
Default unit = 1 motor rev (rotary) 1 pole pitch (linear)
Default PEU = 4000
