Cable Extension

1. Insert the shaft into the coupling.
2. Secure the Rotary Encoder.
3. Secure the coupling.
4. Connect the power and I/O lines.
5. Turn on the Rotary Encoder and check the output.
When extending the cable, select the type carefully. You must
consider the response frequency because the longer the cable
is, the more the residual voltage increases due to the
resistance of the cable and the capacitance between the
wires. As a result, the waveform will be distorted.
We recommend the line driver output type model if the cable
needs to be extended.
In order to reduce inductive noise, the cable must be as short
as possible, especially when the signal is input to an IC.
Insert a surge absorber between the power supply terminals if
a possibility of surge exists.
A wrong pulse may be generated when the E6C2-C Rotary
Encoder is turned on or off. Do not use the connected device
for 0.1 s after the E6C2-C Rotary Encoder is turned on and for
0.1 s before the E6C2-C Rotary Encoder is turned off.
The rise time of each output waveform will increase when the
cable is extended. This affects the phase difference
characteristics of phases A and B.
The available length of cable varies with the response
frequency and noise. It is safer to limit the length of cable to
10 m maximum. If a longer cable of up to 100 m is required,
use line driver output.
Do not secure the coupling and shaft with screws at this
stage.
Refer to the following table for the maximum insertion length
of the shaft into the coupling.
Be sure to turn off the Rotary Encoder when connecting the
lines.

The rise time varies with the resistance of the cable and the
type and length of the cable.
The residual output voltage will increase according to the
length of the cable.
If the operation of the E6C2-C Rotary Encoder is stopped near
a signal rising or falling edge, a wrong pulse may be
generated, causing the E6C2-C Rotary Encoder to miscount.
In this case, use an increment-decrement counter to prevent
miscounting.
Be sure to use a twisted-pair cable to extend a line driver
cable. Use an RS-422A receiver for the receiver side.
The twisted-pair wires as shown in the following illustration are
suitable for RS-422A signal transmission. Normal mode noise
can be eliminated by twisting the wires because the generated
electrical forces on the lines cancel each other.
Be sure the E6C2-C Rotary Encoder is supplied with 5 VDC
when a line driver output is used. There will be approximately
a 1-V voltage drop if the cable length is 100 m.
