1. INTRODUCTION

The 6KCV301ENC card is an AV300i drive option used to add a second
optocoupled encoder input and an encoder repeater to the drive. It is possible
to use only one I/O expansion card per Drive.

This option card features:

- 1 optocoupled digital encoder input

- A / A not +5V or 15V/24V selectable (150kHz max)

- B / B not +5V or 15V/24V selectable (150kHz max)

- C / C not +5V or 15V/24V selectable (150kHz max)

- Encoder qualifier input (QC+ / QC -) 15VDC up to 24VDC

Encoder loss detection is available only when a differential encoder is used
with a 15V – 24VDC power supply

- 1 optocoupled encoder data repeater TTL (@5V) and HTL (@15….24V)

- A / A not +5V and 15V/24V (150kHz max)

- B / B not +5V and 15V/24V (150kHz max)

- C / C not +5V and 15V/24V (150kHz max)

- Encoder qualifier (home position signal) input (QC+ / QC not) 15VDC
up to 24VDC

Encoder repeater has frequency divider functionality selectable between 1,
2, 4, 8 times using hardware jumpers.

2. MOUNTING

The 6KCV301ENC card is supplied with standoffs and the cable for
connection between regulation and expansion card .

1. Switch the drive off.

2. Fasten the 6KCV301ENC card to the drive regulation board by means
of screws (B) and standoffs (A).

3. The 6KCV301ENC card is connected to the regulator card through the
XH connector using the supplied cable. The power supply (+5V) and the
control signals are provided by the drive via the XH connector.

4. Switch on the drive.

3. ENCODER CONNECTOR

3.1 ENCODER INPUT

The 6KCV301ENC expansion board is used to add an additional digital
encoder input through a 15 pin high density connector (VGA type). An external
power supply for the encoder type (+5V or +15V/24V) is needed. Terminal
points 93,94,95 are used to connect an external power supply.

3.2 ENCODER REPEATER CONNECTOR

The optocoupled encoder repeater interface allows the encoder data repeater
simultaneously with TTL level and HTL level through a 15 pin high density
connector (VGA type). An external power supply (+15V/24V) is needed
through terminals 96,97.. This power supply is also needed for the +5V
repeater.

TTL driver are self protected against short circuit for 1 sec, after this time
the drivers could be damaged. HTL driver are protected against short circuit
through 375mA fuse Bussman MCR 3/8 type. An external protection is
recommended with external power supply using 500mA fuses at least.

3.2.1 Divider for encoder repeater

The board has jumpers to set a divider ratio between the encoder repeater
frequency compared to the encoder input data.

The following divider settings are available: /1, /2, /4, /8.
The following table describes the phase shift between input and output.

Divider Description

A out channel is in phase with A in channel

/1

B out channel is in phase with B in channel
C out channel is in phase with C in channel
A out channel edges are phased with either rising or falling edges
of A in (depending on initial condition)
B out channel edges are phased with either falling or rising edges

/2

of A in (depending on initial condition)
C out channel raising edge is in phase with rising edge of C in
and the falling edge after two edges of A in and/or B in
A out channel is in phase with falling edge of A in channel
B out channel is in phase with falling edge of A in channel

/4

C out channel rising edge is in phase with rising edge of C in
and the falling edge after five edges of A in and/or B in
A out channel is in phase with falling edge of A in channel
B out channel is in phase with falling edge of A in channel

/8

C out channel rising edge is in phase with rising edge of C in
and the falling edge after nine edges of A in and/or B in
