P024 (H18)

Cycle time % R/W
Function: The Cycle Time is the time which the Thyristor modulates to obtain the power
demand
Min/Max: 0 ÷ 255 (0 ÷ FF Hex)
Value: Each step is 50msec
Default: 60 (3C Hex) = Zero Crossing
240 (F0 Hex) = Burst Firing
Example: With a Cycle time at 4 sec:
25%-> 1sec 0n+3sec off
50%-> 2sec 0n+2sec off
75%-> 3sec 0n+1sec off

P026 (H1A)

Proportional Band % R/W
Function: This parameter is the gain of the feed-back loop
Min/Max: 0 ÷ 255 (0 ÷FF Hex)
Value: 0 ÷ 255
Default: VxI or V2 = 5 Hex
V or I =12 Hex
Example: -
Note: This parameter increase the loop speed but decrease the loop stability.
P027 (H1B)

Integral Time % R/W
Function: This parameter is the integral time of the feed-back loop
Min/Max: 0 ÷ 255 (0 ÷FF Hex)
Value: -
Default: 50 Hex
Example: -
Note: If you increase integral time you increase the output stability, but you increase
also the time to reach the set.
P028 (H1C)

HB delay Sec R/W
Function: This parameter set a delay to have HB alarm active
Min/Max: 0 ÷ 255 (0 ÷FF Hex)
Value:
Default:
Example:
Note:
P029 (H1D)

HB sensitivity % R/W
Function: This parameter defines the threshold of resistance that activates the HB alarm
This value is in percentage respect the nominal resistance load value
Min/Max: 0,0 ÷ 100,0%
Value: -
Default: 100,0
Example:
…….

=20. This means that the Heather Break Alarm became active when
the current goes below 80A
