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.
