Parameter Descriptions
HIPER COUNT/REV
Range: Enumerated -see below
Hiperface counts per revolution. This scales the Sin Cos encoder to have the equivalent number
of lines as on incremental encoders. Setting a value of 32768 is equivalent to having an 8192
line encoder (32768 counts per revolution).

1ms CYCLE RATE
Range: FALSE / TRUE
Setting this TRUE boosts the execution rate of the phase loop to 1ms, thus improving response.
Note:
Changing from 1ms back to the block diagram rate may make the loops
unstable.
MAX SPEED
Range: 0 to 32000 upm
This is used to scale the velocity feed forward terms from the PHASE INCH, PHASE MOVE
and PHASE REGISTER blocks. It is important that this matches the full speed of the drive.
The units “upm” (units per metre) can be set to some practical unit for the application - refer to
the COUNTS PER UNIT parameter.
MASTER SCALE A
Range: -30000 to 30000
The master encoder counts are scaled by MASTER SCALE A and MASTER SCALE B where
A is the multiplier and B is the divisor.

SLAVE INVERT
Range: FALSE / TRUE
Inverts the sign of the slave encoder input at source when set to TRUE.
MASTER INVERT
Range: FALSE / TRUE
Inverts the sign of the slave encoder input at source when set to TRUE.
