Low I time 2
Range: 5 to 255 cycles Default: 50 cycles Scaling: 1 Type: R/W
‘Low Current Time 2’ – Use with 2nd parameter set.
‘Low Current Time 2’ sets the number of cycles for which an Under Current situation must exist
before tripping.
(P-29 ‘Low Current Time’ is the 1st parameter set counterpart of P-88 ‘Low Current Time 2’.)
C/L 2
Range: 0.375 to 7.9688 xI
e
Default: 4 xI
e
Scaling: 0.03125 Type: R/W
‘Current Limit Level 2’ – Use with 2nd parameter set.
‘Current Limit Level 2’ 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
available
in Bypass Operation unless a user-supplied external current
transformer is installed. (Refer to P18/B2, ‘Auto Bypass’.)
(P-30 ‘Current Limit Level’ is the 1st parameter set counterpart of P-89 ‘Current Limit Level 2’.)
C/L Time 2
Range: 5 to 255 seconds Default: 15s Scaling: 1 Type: R/W
‘Current Limit Time 2’ – Use with 2nd parameter set.
‘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-31 ‘Current Limit Time’ is the 1st parameter set counterpart of P-90 ‘Current Limit Time 2’.)
Shearpin 2
(external CT required for bypass mode; see P-86/Bit-2 for note)
Range: 1.063 to 5 x I
e
Default: 3 x I
e
Scaling: 0.03125 Type: R/W
‘Shearpin Level 2’ – Use with 2nd parameter set.
‘Shearpin Level 2’ 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-32 ‘Shearpin Level’ is the 1st parameter set counterpart of P-91 ‘Shearpin Level 2’.)
Shear time 2
(external CT required for bypass mode; see P-86/Bit-2 for note)
Range: 5 to 255 cycles Default: 50 cycles Scaling: 1 Type: R/W
‘Shearpin Time 2’ – Use with 2nd parameter set.
‘Shearpin Time 2’ sets the number of cycles a Shearpin Current must be present before tripping.
The shearpin is only active during the running phase; not Start or Stop. The shearpin flag (P-95 /
Bit 3) is updated even if tripping is not enabled.
«•» This parameter is not
available
in Bypass Operation unless a user-supplied external current
transformer is installed. (Refer to P18/B2, ‘Auto Bypass’.)
(P-33 ‘Shearpin Time’ is the 1st parameter set counterpart of P-92 ‘Shearpin Time 2.’)
