Incremental Pulse Encoders
The default settings for the drive are for 2048 line, quadrature,
incremental pulse encoders with differential outputs operating
from a 10VDC supply.
• Z channel (Marker pulse) connections are not necessary for
running the drive, but inputs are provided for positioning
and servo applications. The supply voltage to the encoder
is set in the Quick Setup menu. Range 10 VDC to 20 VDC
Use the Keypad to set the following options:
Supply Voltage - PULSE ENC VOLTS (S17)
Number of lines per revolution - ENCODER LINES parameter
(S18)
* Encoder direction - ENCODER INVERT (S19)
* Used to match the encoder direction to the motor direction.
When TRUE, changes the sign of the measured speed and the
direction of the position count. It is necessary to set up this
parameter when in CLOSED-LOOP VEC mode, as the encoder
direction must be correct for this mode to operate.
Using other types of encoders requires the DSE Configuration
Tool and the setting of other parameters. Refer to the 890
Engineering Reference Manual for details of these parameters.
This section is only for closed loop vector and induction servo applications.
Skip this page if there is no encoder or resolver mounted on the motor.
