The built-in power supply of the SERVOPACK can be used. With an external power supply, a photocoupler
isolation circuit will be used. A non-isolated circuit will be used if the built-in power supply is used.
represents twisted-pair wires.
(4) Electrical Specifications for Pulse Train Reference
Forms of pulse train references are as shown below.
Maximum reference frequency by each multiplier are as follows.
×1 input pulse multiplier: 1 Mpps
×2 input pulse multiplier: 1 Mpps
×4 input pulse multiplier: 1 Mpps
• Use a shielded cable for I/O signals and ground both ends of the shield.
• Connect the shield at the SERVOPACK to the connector shell so that the shield will
be connected to the frame ground (FG) through the connector.
