A+ A+ pulse signal input
• Pulse signal inputs from the PG
•
Signal inputs from complementary and open-
collector outputs
• Signal level
H level: 8 to 12 V
L level: 2.0 V or less
A– A– pulse signal input
B+ B+ pulse signal input
B– B– pulse signal input
Z+ Z+ pulse signal input
Z– Z– pulse signal input
SD NC pin (open) For use when cables shields should not be grounded
FE Ground Used for grounding shielded lines

IP PG power supply
• Output voltage: 12.0 V ± 5%
•
Max output current: 200 mA
<1>
IG PG power supply common
AO A pulse monitor signal • Outputs the monitor signal for the A, B, and Z
pulses from the PG speed control card
•
For open collector outputs from the option
• Max voltage: 24 V
• Max current: 30 mA
BO B pulse monitor signal
ZO Z pulse monitor signal
IG Monitor signal common
<1> A separate UL Listed class 2 power supply is necessary when the PG requires more than 200 mA to operate.
PG-B3 Wire Gauges and Tightening Torques
Wire gauge and torque specifications are listed in Table 7.3. For simpler and more reliable wiring, use crimp ferrules on the
wire ends. Refer to the option manuals for the wire size and torque specifications of other options.
