Vatech pDRIVE CX profi - Level of 1 St Overload Restriction; Rate of 1 St Decel. at Overload Restriction; Selection of 1 St Overload Restriction; Selection of 2 Nd Overload Restriction

Operating & Mounting instructions – 8 074 143.03/03 – Page 37
Parameters
b021
Selection of 1st overload restriction VIC 00 to 02 01
This parameter defines when the current limitation is active.
Setting Function
00 not active
01 during acceleration and constant speed
02 only at constant speed
b022
Level of 1st overload restriction VIC 0,5...1,5 x I
FI 1,20 x IN
Defines the value in amperes at which the inverter tries to reduce the load by decreasing the output
frequency.
b023
Rate of 1st decel. at overload restriction VIC 0,10...30,00 s 1,00 s
When reaching the adjusted current limit, the frequency is reduced according to the set ramp.
b024
Selection of 2nd overload restriction VIC 00 to 02 01
b025
Level of 2nd overload restriction VIC 0,5...1,5 x I
FI 1,20 x IN
b026
Rate of 2nd decel. at overload restriction VIC 0,10...30,00 s 1,00 s
With the parameters B021...b023 and b024...b026 two different overload restrictions can be set.
The switch-over is done via a digital input (OLR: C001...C005 = 39).

Note:
The overload restriction is not active during deceleration.
