Puller - Encoder Output

A 2,048-pulse quadrature encoder is built into both puller servomotors. The drives

have the motor encoder as an output on a 44-pin 'D' connector. Scaling is provided

to set the amount of pulses that are outputted per motor revolution. Any integer

number between 1 and 2,048 may be set.

In this application the output on the 44-pin 'D' connector is used by a PLC

(Programmable Logic Controller) or multiple PLC's for the Profile/Bump/Taper

Mode. The PLC's can accept a maximum frequency of 20KHz. A motor at 5,000-

RPM maximum with a 2,048 pulse per revolution encoder will output 170,667

Hz. This far exceeds the capability of the PLC (Programmable Logic Controller).

Instead, the setting of 256 counts per revolution will be used.

To change the amount of Puller Encoder Output counts per revolution:

1 Press the Puller section’s Encoder Output Counts Per Revolutions

window. A numeric pop-up keyboard appears.

2 Key in the counts per revolution amount. This is the counts per revolution

the puller’s encoder output will make.

3 Then press “Enter”. The pop-up keyboard is removed.

NOTE: For applications that

do not have the

Profile/Bump/Taper mode

any value may be set.
