Stop on Trip Masks

Bit SP
Coding
1
Default On (1)
Update rate Background read
The user can mask some of the trips from tripping the drive. The trip can be completely masked (do nothing in the event of the selected trip) by setting
the trip number into the parameter. The trip can be made to stop the drive and then trip, by enabling the associated bit parameter.
Trips that cannot be masked are UV, AOC, AtL.Err, PS, O.SPd, FOC, O.ht1, O.ht2, O.ht3, EEF, SLX.HF, S.OV, PLL Err, Enc9, SLAVE.Er and HF17 to
HF29.
Example 1.
The user wants the drive to not trip when there is current loss on analog input 2. Enter 28 into Pr 10.52 and set Pr 10.62 to 0.
Example 2.
The user wants the drive to stop and then trip when there is current loss on analog input 2. Enter 28 into Pr 10.52 to achieve this.
10.72

Trip Mask Active

Bit SP
Coding
1
Range 0 to 1
Default 0
Update rate Background write
Set to 1 when a trip is being masked.
10.73

Bridge Active

Bit SP
Coding
Range 0 to 2
Default 0
Update rate Background write
This parameter will indicate which bridge is on.
"__ "No bridge
"_1 "Bridge 1 active
"2_ "Bridge 2 active
Where _ is a blank.
10.74 Electrical phase back
Bit SP
Coding
1
Range 0 to 1
Update rate Background read
When 0 the firing pulses not phased back. When 1 the firing pulses are phased back or the drive disabled.
10.75 Armature voltage clamp active
Bit SP
Coding
1
Range 0 to 1
Update rate Background read
Sets to 1 when the armature voltage clamp is activated. Prevents the voltage from increasing further.
When the armature voltage exceeds 1.15 times the supply voltage the armature voltage clamp is activated to prevent the voltage rising. SCR firing is
inhibited until the voltage has fallen.
