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 mm2)
NOTE

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 90o angle.
 Always use and operate this product within the limit of its
specifications.

注意事項
 連接電感性負載（繼電器，電磁接觸器，馬達等）時，請加裝
火花消除器(RC network or Varistor)於線圈側。
 基於安全考量，請於迴路內加裝保險絲（規格不可大於接點限
制）。
 儘可能使用隔離線（隔離層接於大地），以避免干擾。
 線頭請吃錫或打端子。
 基於安規上的考量，配線請保持獨立且與其它控制線，馬達
線，電源線等保持 15cm 以上距離，如有交錯的必要請保持垂
直配線。
 任何時刻的操作皆不可超過規格上的限制。
