Via optional cards, such
as I/O card, Relay card,
PG (Encoder) card and
USB card, to meet your
application requirements

Removable Keypad

The standard keypad
acts as a status monitor.
More functions, including

parameter modication,

RUN/STOP, speed
change, and status
display, are available via
an optional keypad

Sh ielded l eads & Cable

It is recommended to install a circuit breaker at the control terminal to protect the circuit from an operation
abnormality or sudden power outage.

The protection circuit uses the multi-function output terminal of the AC motor drive for connection. When an
abnormal condition (closed contact) occurs, the external power supply is disconnected to protect the power
system of the AC motor drive.
