IAI ERC Series Quick Start Manual

1. Parts Confirmation

Please contact your sales representative if any of these parts are missing or incorrect:
- ERC Actuator: Slider type (ERC-SA6/SA7) or Rod type (ERC-RA54/RA64)
- Relay Cable: CB-ERC-PWBIO***
- CD with Manuals (PDF format)
Optional: - Teaching Pendant
RCA-T/E

2. Installation

a. Install the Actuator.
Screw diameter
Standard torque
for bolting
b. Mount to the Actuator.
- Slider Type: Use the 4 tapped holes (M5, depth 10mm) located on the top of the slider.
The maximum torque for mounting is 7.5Nm (0.77Kgf.m).
- Rod Type: Be sure to use a wrench to prevent adding rotational moment
to the rod (see picture to the right). Use a 13mm wrench for the RA54
model and a 17mm wrench for the RA64 model.

3. Wiring

Connect the connector end of the relay cable to the actuator cable connector.
Individually connect the open ends of the cable to: (1) 24V DC control/motor power supply, (2) Emergency stop circuit,
(3) I/O circuit, (4) Ground wire, (5) Brake release switch (when brake option is used).
Because the HOLD signal is a normally closed contact, it is ON during operation and OFF during pause. If there is no
PLC software at the time of adjustment, change parameter #15 (refer to the last page of this Quick Start Guide). You
can temporarily short it to 0V. (It becomes necessary to use the teaching pendant or PC for operation). Afterwards,
you must remove this short if you plan to automatically operate it with a PLC.

4. LED Indicator for Power Supply

Before supplying 24V power, confirm that the brake release switch is OFF and that the
emergency stop circuit is not operating. Supply power. The LED located on top of the
motor cover should be GREEN.
A RED light indicates a cutoff in the motor power supply, or that an alarm is occurring. At this
point, you should refer to the "Troubleshooting" section of your Operating Manual to resolve
this problem.
