Magpowr DIGITRAC
2 Instruction Manual - page 11

PROPORTIONAL GAIN (33)

Generates an output adjustment proportional to the error.

START TIME (22)

Provides a soft-start when starting with a slack web.  The output is

limited to the HOLD LEVEL at start, but the limit level is increased with

time.  This is the time taken to increase the limit to full output.  A longer

start time will provide a softer start.

STOP MULTIPLIER (24)

Upon receipt of a stop signal, the output is increased by this multiplier

(1 creates no increase).  Since the output is proportional to roll

diameter, this is a simple adjustment for roll inertia.

STOP TIME (23)

This is the time that DIGITRAC 2 stays in STOPPING (automatic)

mode after the stop signal is received.  At the end of this time the

control goes to HOLD mode.  Stop time should be slightly longer than

actual machine stopping time.
