Analog servo interface unit
(basic unit)
Battery for separate detector
(M3 terminal)
Connector:
PCRE20FS or PCRE20FA
Housing: PCRV20LA
Cable connection (J37)
NOTE
Although the expansion unit also has connector JA4M for
connecting the battery for a separate detector, this
connector is normally not used. When the basic unit is
replaced, a battery for the separate detector can also be
connected to JA4M to continuously supply the battery
voltage to the absolute pulse coder connected to the
expansion unit.
1. VCMD, EC (output)
VCMD and EC are the speed command signals for the servo amplifier.
The voltage of VCMD with respect to EC represents the speed
command voltage. (The speed command voltage is enabled only
while the *ENBL signal is on.)
Electrical characteristics
Output voltage : 10 V to +10 V
Output current : 2 mA
Output impedance : 100 ohms
