2-6 Description of Operation
Mode 21
LINE SPEED REFERENCE
When the Drive is in a normal run (Mode 1) or accel cycle (Mode 4),
the Drive will follow the press speed reference.
Mode 22
PRESET 1 SPEED REFERENCE
When the Drive is in auto slack with the web tight (Mode 7), the
Drive will follow the Preset 1 speed reference. This is a low forward
speed reference which is adjustable in Drive Parameter 633.
Mode 23
PRESET 2 SPEED REFERENCE
When the Drive is in run reverse, dancer high (Mode 9), the Drive
will follow the Preset 2 speed reference. This is a low reverse speed
reference which is adjustable in Drive Parameter 634.
Mode 24
TORQUE SELECT
The torque select Parameter in the Drive (Parameter 625) is normally
set so the Drive is a velocity regulator. When running in auto slack
with the dancer in the full up position, the torque select Parameter is
set to zero which is zero torque command. This prevents any motor
armature current and torque while keeping the Drive energized with
the main contactor picked up. This will prolong contactor life by
eliminating the cycling ON and OFF of the contactor during web up.
Mode 25
TORQUE SELECT
TORQUE REFERENCE REVERSE
This mode is used for reverse run only. When in logic Mode 9, the
Drive will run slowly in reverse at preset 2 speed reference until
dancer is centered, then reference will change to torque mode with
zero torque command. This prevents motor armature current and
torque while keeping the Drive energized with the main contactor
picked up.
Mode 26
PROCESS TRIM DISABLE
Any time the Drive is in the paste cycle, the dancer trim is disabled.
This allows the Drive to run from the velocity reference only. The
velocity reference could be zero or press speed reference.
