Î
MOTORIZED POT (It assigns the function of up and down
speed reference to two of the digital inputs. DI5 = Up (NO Contact)
and DI6 = Down (NC Contact). Reference is memorized)

Î
ERASAB POT (As per above mode without memorizing the
reference).

Î
Start/Stop (Allows the start/stop command to be given by a
switch).
G5: Inputs: Acceleration and Deceleration Ramps.
7 PMT ACL1=1.0% / s
G5.7
/ Ramp 1 of reference increase for
motorized potentiometer
1.0% / s (Modify these ramps to tune operation). If the ramp is
increased the speed reference response will be faster. If the ramp
is decreased the speed reference response will be slower.
8 PMT DCL1=3.0% / s
G5.8
/ Ramp 1 of reference decrease for
motorized potentiometer
3.0% / s (Modify these ramps to tune operation). If the ramp is
increased the speed reference response will be faster. If the ramp
is decreased the speed reference response will be slower.
