PRIMARY-42: Speed Reference in Auto
Auto Speed Ref
42) Keypad 0 - Keypad
1 - 1A Analog Input
2 - 2A Analog Input
3 - Comms
4 - PID
5 - 3A Analog Inputs
Default: (0) Keypad
Selection for speed reference source in Auto
mode. 1A input 0 ‐ 10VDC or 4 ‐ 20mA type will be
set by 1A DIP switch. 2A input is always 0 ‐ 10V.
2A selection is available when 2A DIP Sw is set to
Input. When set to PID, all PID parameters will be
available.
Keypad
When VFD HOA Auto key is pressed or external
HOA SW is put in Auto position, VFD will provide
output frequency corresponding to a reference
given via VFD keypad.
1A Input
Provides frequency reference via 1A Input set by
DIP Sw to 4 ‐ 20mA or 0 ‐ 10VDC (scalable in I/O
group). If DIP Sw is in 24V position, processor still
treats it as 0 ‐ 10VDC because it will be scaled to
that level by hardware components.
2A Input
Provides frequency reference via 2A Input set by
DIP Sw to 0 ‐ 10VDC input (scalable in I/O group).
3A Input
Provides frequency reference via 3A Input set by.
Communications
When Communication is selected as a speed
reference source, VFD will provide output
frequency based on reference set by
communications.
PID
VFD speed reference will be provided by PID
control based on difference between PID Set ‐
point and Feedback values. When set to PID, all
PID parameters will be available. When PID
mode is enabled, DC trip prevention, stall
prevention and skip frequencies are disabled.
PRIMARY-43: Reference Loss Condition
Anlg Ref Loss
43) Half of Min 0 - Disabled
1 – Below ½ of Min
2 – Below Min
Default: (1) Half of Min
Select either below minimum value, or below
half of minimum value of the analog signal
selected as a speed reference loss condition.
PRIMARY-44: Reference Loss Action
Anlg Ref Loss Act
44) Stop 0 - Fault
1 - Stop
2 - Hold Speed
Default: (1) Stop
Select a VFD action at signal loss:
0 ‐ Fault= VFD trips and manual reset or
rebooting is required;
1 ‐ Stop = VFD stops using the stop mode
defined in BASIC 30; Provides auto restart when
signal value is equal or greater than Reference
Min value, and run command is present.
2 ‐ Hold = VFD runs at previous speed.
