Safety Precautions
Do not impose voltage exceeding the rated voltage range on the
E6C3, otherwise the E6C3 may be damaged.
Do not wire power lines or high-tension lines along with the power
supply lines of the E6C3 or the E6C3 may be damaged or malfunc-
tion.
If the power supply has surge voltage, connect a surge suppressor
between the positive and negative terminals of the power supply to
absorb the surge voltage. Also, in order to protect the E6C3 from
noise, shorten the wires connected to the E6C3 as much as possi-
ble.
Unnecessary pulses are output at the time the E6C3 is turned ON or
OFF. After turning ON the E6C3, be sure to wait 0.1 s before turning
ON the peripheral devices connected to the E6C3 and turn OFF the
peripheral devices 0.1 s before turning OFF the E6C3.
Application Precautions
Mounting
● Mounting Precautions
• Be careful not to spray water or oil onto the E6C3.
• The E6C3 consists of high-precision components. Handle with
utmost care and do not drop the E63C, otherwise malfunctioning
may result.
• When the E6C3 is used in reversed operation, pay utmost attention
to the mounting direction of the E6C3 and the directions of incre-
ment and decrement rotation.
• To match phase Z of the E6C3 and the origin of the device to be
connected to the E6C3, conform the phase Z outputs while con-
necting the device.
• Be careful not to impose an excessive load on the shaft if the shaft
connects to a gear.
• If the E6C3 is mounted with screws, the tightening torque must not
exceed approximately 0.5 N·m.
• If the E6C3 is mounted to a panel, do not pull the cable with more
than a force of 30 N. Do not subject the E6C3 or the shaft to exces-
sive shock.
• When connecting the coupling, stay within the ranges shown
below.

• When connecting or disconnecting the coupling, do not impose an
excessive bending, pressing, or pulling force on the E6C3.
• When connecting the shaft of the E6C3 with a chain timing belt or
gear, connect the chain timing belt or gear with the shaft via the
bearing and coupling as shown in the following illustration.

• If the decentering or declination value exceeds the tolerance, an
excessive load imposed on the shaft may damage or shorten the
life of the E6C3.

• No shock must be given to the shaft or coupling. Therefore, do not
hit the shaft or coupling with a hammer when inserting the shaft
into the coupling.
