To use the encoder a encoder interface card (such as SL-PG0) is needed. The wiring of the card is
described in detail in Chapter 9.
Fd-02: If single-channel encoder is selected, the signal must enter from channel A. Single-channel
encoder is not applicable to low-speed operations and operations with both forward and reverse
directions.
Fd-03: For a single-channel encoder, if positive direction is selected, then FU-35 is always positive,
otherwise always negative.
PG disconnection: PG is regarded to be disconnected if the reference frequency of the speed regulator
is greater than 0.5Hz and the encoder fails to generate a pulse within the time set by Fd-05. The motor
act according to the setting of Fd-04. PG disconnection detection is performed only for PG V/F control
and PG vector control.
In application where the encoder is connected to the motor shaft via speed changing devices such as
gears, Fd-06 and Fd-07 must be correctly set. The relationship between the encoder speed and motor
speed is: Motor speed=encoder speed×Fd-07÷Fd-06.
Fd-08 should not be too large if a high dynamic performance is required.
Related monitored parameter: FU-35.
Method of verifying the encoder setting: Adopt PG V/F control mode and run the motor in the
direction and at the frequency which are allowed by the load, check to see if the direction of FU-35 is
consistent with the direction displayed on the keypad, and if the value of FU-35 is close to the reference
frequency.
Danger: PG parameters must be set correctly in control modes with PG, otherwise injury to people and
damage to equipment may occur. The setting of the encoder direction must be rechecked after
the motor cables are rewired.
