1. SPECIFICATIONS OF MOTION SYSTEM COMPONENTS
(b) Connection of manual pulse generators/synchronous encoders
Manual pulse generators are available in voltage output type and differential
output type, and synchronous encoders are available in voltage
output/differential output type and serial absolute output type (Model: MR-
HENC). Since these types differ in connectors and connection methods, design
according to the connection system described below. (The synchronous
encoders are used only in the SV22 virtual mode.)
In addition, the usable numbers of manual pulse generators and synchronous
encoders differ between the CPU modules.

1) Connection of voltage output type and differential output type manual
pulse generators and incremental synchronous encoders
Use the PULSER connector at the A172SENC module front to connect any
of the voltage output type and differential output type manual pulse
generators and incremental synchronous encoders.
The pin layout and connection of the PULSER connector are described
below.

generator, as described below.
*2 Voltage -output type
Connect the A-phase signal to Pin 4 (HA1) and the B-phase signal to Pin 14 (HB1).
*3 Differential-output type
Connect the A-phase signal to Pin 7 (HA2P) and the A-phase inverse signal to Pin 17 (HA2N), the B-
phase signal to Pin 8 (HB2P) and the B-phase inverse signal to Pin 18 (HB2N).
