4.1.7 Connector and Wiring Notes
Note 1 - Buffered Encoder Outputs
Each of the encoder output pins on P3 is a buffered pass-through of the corresponding input signal on P4,
Refer to section 4.2.2 “Buffered Encoder Outputs”. This can be either from a motor mounted encoder or
an encoder emulation of the resolver. The parameter “Resolver Tracks” configures the resolution of the
encoder emulation (refer to 5.3.17).
Note 2 - Master Encoder Inputs or Step/Direction Inputs
An external pulse train signal (“step”) supplied by an external device, such as a PLC or stepper indexer, can
control the speed and position of the servomotor. The speed of the motor is controlled by the frequency of
the “step” signal, while the number of pulses that are supplied to the PositionServo determines the position
of the servomotor. Direction input controls direction of the motion.
Note 3 - Digital Input A3
For the drive to function, an ENABLE input must be wired to the drive, and should be connected to IN_A3,
(P3.29), which is, by the default the ENABLE input on the drive. This triggering mechanism can either be
a switch or an input from an external PLC or motion controller. The input can be wired either sinking or
sourcing (section 4.2.3). The Enable circuit will accept 5-24V control voltage.
