Chapter 3 Connections and Wiring
3-26 Revision January 2011
3.4.2 Signals Explanation of Connector CN1
The Tables 3.A, 3.B, & 3.C detail the three groups of signals of the CN1 interface. Table
3.A details the general signals. Table 3.B details the Digital Output (DO) signals and Table
3.C details the Digital Input (DI) signals. The General Signals are set by the factory and
can not be changed, reprogrammed or adjusted. Both the Digital Input and Digital Output
signals can be programmed by the users.

V_REF 42
1. Motor speed command: -10V to +10V,
corresponds to -3000 ~ +3000 r/min speed
command (Factory default setting).
2. Motor speed command: -10V to +10V,
corresponds to -3 ~ +3 rotations position
command (Factory default setting).

Monitor operation status: Motor characteristics
such as speed and current can be represented
by analog voltages. The drive provides two
channels which can be configured with the
parameter P0-03 to output the desired
characteristics.
Please reference the parameter P0-03 for
monitoring commands and P1-04 / P1-05 for
scaling factors.
Output voltage is reference to the power
ground.

The drive can accept two different types of
pulse inputs: Line-driver input (max. input
frequency is 500Kpps) and Open-collector input
(max. input frequency is 200Kpps).
Three different pulse commands can be
selected via parameter P1-00. They are A phase
+ B phase (Quadrature), CW pulse + CCW pulse,
and Pulse + Direction.

When an Open-collector type of pulse is used,
this terminal must be connected to a pull-up

The drive can accept two different types of
high-speed pulse inputs: +5V input and Line-
driver input. The max. input frequency is
4MHz.
Three different pulse commands can be
selected via parameter P1-00. They are A phase
+ B phase (Quadrature), CW pulse + CCW pulse,
and Pulse + Direction.
