B.6 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.
14 INV MIN ALARM: Opens when the feedback signal exceeds the MIN ALARM setting.
15 INV MAX ALARM: Opens when the feedback signal falls below the MAX ALARM setting.
16 INV MIN/MAX ALARM: Opens when the feedback signal is within the range defined by the MIN
ALARM and MAX ALARM.
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.
