Position-proportional output (2G)
Connect as follows paying attention to the switching direction:
Handling Precautions
• The life of internal relays is limited.
Avoid setting the PID constant in such a way that results in exces-
sive repeated ON/OFF switching.
• When using a 100/200Vac motor, pay attention to rush current
and the contact rating. If necessary, provide an external auxiliary
relay.
• Separate the wiring for motor terminals and feedback
resistor terminals .
(Do not wire the leads in the same duct or use 6-core cable.
Doing so might result in faulty controller operation caused by
electrical noise when the motor is started up.)
• When controlling without motor feedback with variable param-
eter
M
.-C
set to “2”, terminals need not be connected.
■
Voltage output (6D)
Connect as follows:
Handling Precautions
• Voltage output is reliant on an internal fixed-current circuit.
Set the current value in the setup data so that the optimum volt-
age is obtained matched to the conditions of the SSR in use and
load.
Factory setting: general-purpose SSR voltage value.
