Inovance MD800 Series - Page 321

Parameter Group
-320-
Value Range:
0.0% to 100.0%
Description
The value 100% corresponds to the maximum deviation between the reference and feedback. The
value range is FA-19 (PID parameter switchover deviation 1) to 100.0%.
FA-21
PID initial value
Address:
64021
Min.:
0.0
Unit:
%
Max.: 100.0 Data type: UInt16
Default:
0.0
Change:
At once
Value Range:
0.0% to 100.0%
Description
When the AC drive starts, the PID starts closed-loop adjustment operation only after the PID has
output the initial value (FA-21) for longer than the time set by FA-22 (hold time of PID initial value).
FA-22
Hold time of PID initial value
Address:
64022
Min.:
0.00
Unit:
s
Max.: 650.00 Data type: UInt16
Default:
0.00
Change:
At once
Value Range:
0.00s to 650.00s
Description
When the AC drive starts, the PID starts closed-loop adjustment operation only after the PID has
output the initial value (FA-21) for longer than the time set by FA-22 (hold time of PID initial value).
FA-23
Maximum deviation between two PID outputs in forward direction
Address:
64023
Min.:
0.00
Unit:
%
Max.: 100.00 Data type: UInt16
Default:
1.00
Change:
At once
Value Range:
0.00% to 100.00%
Description
When the deviation between two adjacent outputs is greater than FA-23, the PID output value is the
calculated value plus the value of FA-23.
FA-24
Maximum deviation between two PID outputs in reverse direction
Address:
64024
Min.:
0.00
Unit:
%
Max.: 100.00 Data type: UInt16
Default:
1.00
Change:
At once
Value Range:
0.00% to 100.00%
Description
When the deviation between two adjacent outputs is less than FA-24, the PID output value is the
calculated value minus the value of FA-24.
FA-25
PID integral property
Address:
64025
