■ Function De󶍾nition of the DIP Switch
The DIP switch S1 is used to set the frequency division coe󶎀cient and select the
󶍾ltering function. The code is 1 when the DIP switch is ON, otherwise the code is 0.

NOTE
◆ Non-adaptive 󶍾ltering: The 󶍾lter coe󶎀cient of the PG card is
󶍾xed to a small value. This function is suitable for applications
without signal interference, with small signal interference, or
where the motor runs at high speed.
◆ Adaptive 󶍾ltering: The 󶍾lter coe󶎀cient of the PG card is
adjusted automatically, and the PG card has a strong anti-
interference capability, especially when the encoder feedback
speed is smaller than 60 kHz. This function which is enabled
by default is suitable for applications with strong signal
interference.
◆Fixed interlock: Add the function of eliminating the edge jitter
of the encoder feedback signal compared to the adaptive
󶍾ltering. This function is suitable for applications where the
edge jitter of the encoder feedback signal exists.
◆ Automatic interlock: Compared to the 󶍾xed interlock, add
the automatic switchover between the adaptive 󶍾ltering
and the 󶍾xed interlock to adapt to zero-speed and non-zero-
speed working conditions, preventing the problem that useful
signals are eliminated mistakenly as edge jitter in zero-speed
condition.
3. Wiring
■Instructions for Collector Input Wiring
1 ） Connect the encoder output phase A and phase B to the PGA and PGB
terminals of the PG card, respectively, and connect the power cable of the
encoder to the +15PG and COM terminals.
2 ） Connect the shield of the encoder cable to the PE terminal of the PG card.
3 ） Select the 󶍾ltering function according to the applications (The 󶍾ltering
function is selected by numbers 7 and 8 of the DIP switch. For details, see
section 2).
Because the electrical characteristics of the collector can lead to slow rising edge
of signals, the signal transmission distance of the collector encoder does not
exceed 50 m. Therefore, for applications with cable length greater than 50 m, it
is recommended not to use the collector encoder, but to use the push-pull or
di󶍽erential encoders.
■Instructions for Collector Frequency Division Output
Wiring
1 ） Connect the frequency division output cable to the OUT-A/OUT-B/COM
frequency division output terminals of the PG card.
2 ） Set the frequency division coe󶎀cient by numbers 1 to 6 of the DIP switch. For
the speci󶍾c settings, see section 2. The default is 32 frequency division output.
3 ） Connect the shield of the frequency division output cable to the PE terminal of
the device receiving the frequency division signal.
The allowable maximum sink current and maximum pull-up voltage of the collector
frequency division output of the PG card are 300 mA and 30 V, respectively. The
output cannot be directly connected to a 24 V power supply. Otherwise, the PG card
output component will be damaged.

NOTE
◆The cable from the encoder to the PG card must be separated
from the cables of the control circuit and the main circuit.
Parallel cabling with close distance is forbidden.
◆The cable from the encoder to the PG card must be a shielded
cable, with the shield connected to the PE terminal on the AC
drive side (only one end is grounded to prevent interference).
◆The cable from the encoder to the PG card must run through a
separate duct, and the metal shell is reliably grounded.
4. EMC Guidelines
1 ） During on-site installation and commissioning, the signal cables (such as
the encoder cables) and power cables must be laid in di󶍽erent ducts. Never
bundle the encoder cables and power cables together to prevent the encoder
interference.
2 ） The motor housing must be connected to the PE terminal of the AC drive, and
the grounding cable on the side of the motor housing must be connected
properly.
3 ） It is recommended to use the shielded twisted pair cables. For the di󶍽erential
encoder, the cables must be twisted with di󶍽erential pairs and the cable shield
must be connected to the PE terminal of the AC drive.
4 ） For some large-scale equipment, the long motor cable (>10 m) caused by
the long distance between the AC drive and the motor can result in high
inductance, which a󶍽ects the grounding e󶍽ect. In this condition, the encoder
shield needs not to be connected to the PE terminal of the AC drive.
5 ） LED1 on the PG card is used to judge whether interference exists in the
encoder input signal. For details, see the table“De󶍾nition of Signal Indicators”
in section 2.

c. Hardware damage caused by dropping or transportation after
procurement
d. Operations not following the user instructions
e. Damage out of the equipment (for example, external device factors)
3 ） The maintenance fee is charged according to the latest Maintenance Price List
of Inovance.
4 ） If there is any problem during the service, contact Inovance’s agent or
Inovance directly.
