„ Wiring the PG-B2
Wiring examples for the PG-B2 are provided in the following illustrations.
• Shielded twisted-pair wires must be used for signal lines.
• Do not use the pulse generator power supply for anything other than the pulse generator (encoder).
Using it for another purpose can cause malfunctions due to noise.
• The length of the pulse generator wiring must not be more than 100 meters.
• The direction of rotation of the PG can be set in parameter F1-05. The factory preset is Phase A leads
with a forward run command.
Fig 2.25 PG-B2 Wiring
• When connecting to a voltage-output-type PG (encoder), select a PG that has an output impedance with
a current of at least 12 mA to the input circuit photocoupler (diode).
• The pulse monitor dividing ratio can be changed using parameter F1-06 (PG division rate).
• The pulse monitor emitter is connected to common inside the PG-B2. The emitter common must be used
for external circuits.
