U2KV23DN1 Instruction Manual
- -1
1. Specifications
This manual is for Speed detecting option PCB U2KV23DN1.( Card NPQF-DN09). The option allows
the use of a standard complimentary encoder for speed detection feedback.
Encoder specifications:
Item Specifications
Supply voltage 12VDC±1.2V
Output method Complimentary
Output pulse voltage VH(High revel pulse voltage):above 8.0V , VL(Low revel pulse
voltage):below 1.0V at the terminal on V23-DN1.
Supplied current 150mA (Including signal currents) (Refer Note2 on page 2)
Rising/falling time Within 1µs
Output signal 90º±30º phase difference signal(A phase pulse, B phase pulse)
(Refer Note3 on page 2)
Output pulse
frequency The output pulse frequency is required within 60±10kHz when the motor rotates at the max. speed.
2. Installation
a) Confirm that the Jumper W1 on U2KV23DN1 is set to 1(2PP) side.
b) Remove the front cover of VAT2000S
CAUTION
There is a risk of electric shocks.
The VAT2000S has a built-in electrolytic capacitor, so a charge will remain even when the inverter power is turned OFF. Always
observe the following times before carrying out wiring work.
• Wait at least 20 minutes after turning the power OFF before starting work. Make sure that thedisplays on the operation panel
have gone out before removing the cover.
• After removing the cover, confirm that the "CHARGE" LED in the VAT2000S does not light. Also check that the voltage
between terminals L+1 or L+2 and L– is 15V or less before starting the inspections. (Check with the "CHARGE" LED if the
unit is not provided with the L– terminal.)
c) Install U2KV23DN1 to the position Option I on the Control PCB cover and make sure not to bend the
pins of reverse of U2KV23DN1.

3. Wiring
An example of the encoder connection is given below.
Note 1: The option U2KV23DN1 is card number NPQF-DN09.
Note 2: If the current to encoder exceeds 150mA, use an external power supply. In this case, connect
the external power source only to the encoder. DO NOT connect the power source to TB1-
1,2[12KP] or -3[0KP] on U2KV23DN1.
Note 3: Below drawing shows A, B encoder phases when motor rotates forward.
