117
I/O frequency reference selection
(2.1.14)
Defines which frequency reference source is selected when controlled from the I/O control
place.
0 = Keypad reference (Menu M3)
1 = Fieldbus reference
118
PID
controller
gain
(2.9.4)
This parameter defines the gain of the PID controller. If the value of the paramter is set to
100% a change of 10% in the error value causes the controller output to change by 10%. If the
parameter value is set to 0 the PID controller operates as ID-controller.
See examples at parameter ID132 below.
119
PID
controller
I-time
(2.9.5)
The parameter ID119 defines the integration time of the PID controller. If this parameter is set
to 1,00 second a change of 10% in the error value causes the controller output to change by
10.00%/s. If the parameter value is set to 0.00 s the PID controller will operate as PD
controller.
See examples at parameter ID132 below.
120
Motor
cos
phi
(2.1.10)
Find this value “cos phi” on the rating plate of the motor.
121
Keypad frequency reference selection
(2.2.22)
Defines which frequency reference source is selected when controlled from the keypad.
0 Reference from keypad (Freq Ref)
1 Reference from fieldbus
122
Fieldbus frequency
reference selection
(2.2.23)
Defines which frequency reference source is selected when controlled from the fieldbus.
0 Reference from keypad (Freq Ref)
1 Reference from fieldbus
132
PID
controller
D-time
(2.9.6)
The parameter ID132 defines the derivation time of the PID controller. If this parameter is set
to 1,00 second a change of 10% in the error value during 1.00 s causes the controller output to
change by 10.00%. If the parameter value is set to 0.00 s the PID controller will operate as PI
controller.
See examples below.
