I/O Card (EME-A22A)

Installation

Make sure that the AC Motor Drive is powered off before

operation. DO NOT insert or remove the card when the AC
Motor Drive is powered on.

Please mount the extension card as shown and fix it with

the screw packed with the card.

Screw torque:

Maximum 2kgf-cm

Terminals Screw Torque: Maximum 5kgf-cm

Wire Gauge: 14 ~ 24 AWG (2.1 ~ 0.2 mm

2

)

NOTE

Only when the extension card is correctly installed on
the AC Motor Drive, the extension card will be
automatically detected. The parameters can be set in
Group 12. If extension card is not installed, only
parameters Group 0 ~ Group 10 can be set. Refer to
Chapter 5: Parameters in the user manual for further
details.

Notes

When the relays are used to switch inductive loads (relays,

contactors, motors, etc), connect an RC network or Varistor
parallel to the load to suppress voltage spikes.

For safety, it is recommended to use fuses for the circuitry

that is switched by the relays. The fuse specification must
be within the specified contact limits.

Please use shielded wires to avoid interferences and

connect the shield to ground.

The ends of wires must be tinned or crimped.

To avoid interference, route the extension card wires

separately and as far away (at least 15cm) as possible from
other control wires, motor wires and power wires, etc.
Where these wires must cross each other, please make
sure they are at a 90

o

angle.

Always use and operate this product within the limit of its

specifications.
