5. Control Input / Output
5-7
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.

FLT
Fault
This turns ON during a fault.
MC
Charge completed
This turns ON when the DC main circuit voltage reaches full voltage after power ON
RDY1
Ready (1)
This turns ON when there is no fault, EMS is not activated, and pre-charging is done.
RDY2
Ready (2)
This turns ON when there is no fault, EMS is activated and pre-charging is completed.
LCL
Local
This turns ON when the operation mode is local (operation from the operation panel).
REV
Reverse run
This turns ON while the motor is running in reverse direction.
IDET
Current detection
This turns ON when the output current reaches the detection level (C15-1) or higher.
ATN
Frequency (speed)
attainment
This turns ON when the output frequency (speed) reaches the set frequency (speed). The
detection reach width is set with C15-0.
SPD1
Speed detection (1)
This turns ON when the output frequency (speed) absolute value reaches a speed higher
than the speed set with the detection level (C15-2).
SPD2
Speed detection (2)
This turns ON when the absolute motor speed reaches a speed higher than that set in the
detection level (C15-3).
COP
Transmission selec.
This turns ON when serial transmission operation is selected.
EC0~EC3
Fault code 0 to F
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.
ACC
Acceleration
This turns ON during acceleration.
DCC
Deceleration
This turns ON during deceleration.
AUXDV
Auxiliary drive
selection
This turns ON when the auxiliary drive parameter setting is validated by the sequence input
AUXDV.
ALM
Minor fault
This turns ON during a minor fault.
FAN
Fan control
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.
ASW
Automatic start wait
When the automatic start function is enabled by C08-0, ASW will turn ON while waiting for
automatic start.
ZSP
Zero speed
This turns ON when the output frequency (speed) absolute value is below the level set with
zero speed (C15-4).
LLMT
PID lower limit
ULMT
PID upper limit
These turns ON when the feedback value exceeds the limit value (<B43-3) or (>B43-4)
during PID operation
(Note) "ON" indicates that the contact is closed.
