Parameter Descriptions
UP TIME
PREF: 162.04 Default: 1.0 s Range: 0.5 to 10.0s
Determines the rated at which the inverse time current limit is ramped back to the minimum value between 200% of
permanent drive current and MAX CURRENT (refer to MOTOR PMAC 1 Function Block) once the overload is removed.
IT LIMITING
PREF: 162.05 Default: FALSE Range: FALSE / TRUE
This diagnostic indicates if the inverse time current limit is active.
INVERSE TIME OP
PREF: 162.06 Default: —.00 % Range: —.00 %
This diagnostic indicates the present level of current that is allowed as a percentage of STACK CURRENT (refer to the
FEEDBACKS function block), clamped by MAX CURRENT (refer to the MOTOR PMAC 1 function block). Under normal
conditions and when not clamped by MAX CURRENT, this ranges from 110% to 200% of STACK CURRENT, depending
on the frame size and mode as described below. When the drive is limiting, this value will be the AIMING POINT clamped
by either 105% of STACK CURRENT or PERM CURRENT (refer to the MOTOR PMAC 1 function block).
In Quadratic Torque Mode:
Under normal conditions, the drive current limit is set to 110% of STACK CURRENT.
For Frames B, C & D:
Under normal conditions, the drive current limit is et to 200% of STACK CURRENT and DELAY is limited to 4
seconds.
For Mobile Frames:
Under normal conditions, the drive current limit is set to 175% of STACK CURRENT.
For Other Frame Sizes:
Under normal conditions, the drive current limit is set to 150% of STACK CURRENT.
IT WARNING
PREF: 162.07 Default: FALSE Range: FALSE/TRUE
This diagnostic indicates if the reduction is acting or not.
