Introduction

Operating Modes

The 525 PMC offers three standard modes of operation: Indexing, Pulse and Analog.

Indexing Mode

The indexing mode allows up to thirty-two different indexes or positions to be pre- programmed and stored in non-volatile memory. These indexes and other commands such as stop and jog are selected by the drive's input/output (I/O) lines from devices such as PLCs or operator push buttons. I/O connections can be used for stand alone operation or in conjunction with one of the two control modes.

Another powerful feature of the indexing mode allows ASCII serial commands to be received through the standard RS423 serial interface. This interface port allows you to down-load new positional data such as distance, velocity, position etc.. The ASCII serial commands work with the RS232C serial interface on an IBM (or compatible) personal computer (PC) or programmable logic controller (PLC) with an ASCII or basic module.

Pulse Mode

In the pulse mode the 525 PMC responds to a pulse train representing externally generated incremental position change commands. These commands are normally in the form of CW or CCW direction pulses. This mode is commonly used to when replacing stepper motors.

Analog Mode

In the analog mode the 525 PMC responds to a conventional +/- 10 volt signal. Most variable speed drives and servo amplifiers on the market today receive commands via analog input.
