P69
0-10 VDC FEEDBACK
This can be used to monitor the PI feedback when using a 0-10 VDC feedback signal. The displayed
value will be scaled according to the MIN and MAX FEEDBACK parameters (62 and 63).
P70
4-20 mA FEEDBACK
This can be used to monitor the PI feedback when using a 4-20 mA feedback signal. The displayed
value will be scaled according to the MIN and MAX FEEDBACK parameters (62 and 63).
P71
ACTUAL FREQUENCY
This can be used to monitor the actual output frequency of the drive when operating in PI mode, as
the normal display is scaled to PI units according to the MIN and MAX FEEDBACK parameters.

DESCRIPTION OF OTHER PARAMETERS
In addition to the PI feature, two parameters have been added, and additional options have been
added to the open-collector status outputs:
P06/P13
TB-14 / TB-15 OUTPUT
Three more options have been added to the open-collector outputs:
11
MIN ALARM: Opens when the feedback signal falls below the MIN ALARM setting.
12
MAX ALARM: Opens when the feedback signal exceeds the MAX ALARM setting.
13
MIN/MAX ALARM: Opens when the feedback signal falls below the MIN ALARM setting or
exceeds the MAX ALARM setting.
P45
SPEED AT MIN SIGNAL
This sets the speed at which the drive will run when it receives the minimum speed reference signal
(0 VDC or 4 mA). This is used in conjunction with SPEED AT MAX SIGNAL (Parameter 46) to
define the speed range of the drive when following an analog speed reference signal.
P46
SPEED AT MAX SIGNAL
This sets the speed at which the drive will run when it receives the maximum speed reference signal
(10 VDC or 20 mA). This is used in conjunction with SPEED AT MIN SIGNAL (Parameter 45) to
define the speed range of the drive when following an analog speed reference signal.
NOTE: If SPEED AT MIN SIGNAL is set higher than the SPEED AT MAX SIGNAL, the drive will
react inversely to the speed reference signal. Therefore, as the speed reference signal increases, the
drive speed will decrease, and vice-versa.
