Peak Start I
Range: 0 to 255 Amps Default: 0A Scaling: 1 Type: R
‘Peak Start Current’ displays the peak current seen by the unit during the last start.
Scaling is per the running current.
Low I Level
Range: 0.031 to 0.7813 x I
e
Default: 0.0938 x I
e
Scaling: 0.03125 Type: R/W
The ‘Low Current Level’ parameter, if enabled, sets a level of current under which the unit will trip.
This low current trip level is not active during the starting or stopping phases. The Low Current
Level flag (P-112 / B3) is continually updated even if tripping is disabled.
«•» This parameter is not available in Bypass Operation unless a user-supplied external current
transformer is installed. (Refer to P18/B2, ‘Auto Bypass’.)
(P-87 ‘Low Current Level 2’ is the 2nd parameter set counterpart of P-28 ‘Low Current Level’.)
Low I Time
Range: 5 to 255 cycles Default: 50 cycles Scaling: 1 Type: R/W
‘Low Current Time’ sets the number of cycles for which an Under Current situation must exist
before tripping.
(P-88 ‘Low Current Time 2’ is the 2nd parameter set counterpart of P-29 ‘Low Current Time’.)
C/L Level
Range: 0.375 to 7.9688 xI
e
Default: 3.5 x I
e
Scaling: 0.03125 Type: R/W
‘Current Limit Level’ sets the current level at which the the Soft Start ramp will be held.
The Current Limit only holds the ramp if its level is reached.
The current naturally falls as motor speed increases, allowing the ramp to continue.
«•» This parameter is not fully functional in Bypass Operation unless a user-supplied external
current transformer is installed. (Refer to P18/B2, ‘Auto Bypass’.)
(P-89 ‘Current Limit Level 2’ is the 2nd parameter set counterpart of P-30 ‘Current Limit Level’.)
C/L Time
Range: 5 to 255 seconds Default: 30s Scaling: 1 Type: R/W
‘Current Limit Time’ sets the maximum time allowed for the current limit before it trips or
continues the ramp regardless of motor current level.
(P-90 ‘Current Limit Time 2’ is the 2nd parameter set counterpart of P-31 ‘Current Limit Time’.)
Shear Level
Range: 0.5 to 5 x I
e
Default: 3.125 x I
e
Scaling: 0.03125 Type: R/W
‘Shearpin Level’ sets the level of current which will cause a quick trip. Not active during Start or
Stop.
«•» This parameter is not available in Bypass Operation unless a user-supplied external current
transformer is installed. (Refer to P18/B2, ‘Auto Bypass’.)
(P-91 ‘Shearpin Level 2’ is the 2nd parameter set counterpart of P-32 ‘Shearpin Level’.)
