Programmable Sequence Output Function (Pso) - GE VAT2000 Instruction Manual

5-4 Programmable sequence output function (PSO)

As standard, there are five digital outputs in the
VAT2000 (1NO/NC dry contact, one NO dry contact
and three open collector transistor outputs).
The 1NO/NC dry contact output is fixed to fault
output, but the other four channels are
programmable and can be set arbitrarily to any of the
output signals given in Table 5-4.
Two additional dry relay outputs are possible by
Optional PCB interfaces (type: U2KV23RY0 or
U2KV23PI0).
The programmable output provided in VAT2000 as
standard are RA-RC, PSO1, PSO2 and PSO3.
The functions of the programmable output signals are given in Table 5-4.

This turns ON during running, jogging or DC braking.
Turning ON or OFF during pre-excitation can be selected.

This turns ON during a fault.
This turns ON when the DC main circuit voltage reaches full voltage after power ON
This turns ON when there is no fault, EMS is not activated, and pre-charging is done.
This turns ON when there is no fault, EMS is activated and pre-charging is completed.
This turns ON when the operation mode is local (operation from the operation panel).
This turns ON while the motor is running in reverse direction.
This turns ON when the output current reaches the detection level (C15-1) or higher.
This turns ON when the output frequency (speed) reaches the set frequency (speed). The
detection reach width is set with C15-0.
This turns ON when the output frequency (speed) absolute value reaches a speed higher
than the speed set with the detection level (C15-2).
This turns ON when the absolute motor speed reaches a speed higher than that set in the
detection level (C15-3).
This turns ON when serial transmission operation is selected.
This outputs the fault messages with a 4-bit binary code.
EC0 is the low-significant bit, and EC3 is the most significant bit.
Refer to Appendix 3 for details on the fault codes.
This turns ON during acceleration.
This turns ON during deceleration.
This turns ON when the auxiliary drive parameter setting is validated by the sequence input
AUXDV.
This turns ON during a minor fault.
This turns ON during running, jogging, pre-excitation and DC braking. A three minute off
delay is provided.
This is used for external fan control.
When the automatic start function is enabled by C08-0, ASW will turn ON while waiting for
automatic start.
This turns ON when the output frequency (speed) absolute value is below the level set with
zero speed (C15-4).
These turns ON when the feedback value exceeds the limit value (<B43-3) or (>B43-4)
