Microcomputer Section
The main processing unit of the DMC-1500 is a specialized 32-bit Motorola 68340 Series
Microcomputer with 256K RAM, 64 K EPROM and 128 K bytes EEPROM. The RAM provides
memory for variables, array elements and application programs. The EPROM stores the firmware of
the DMC-1500. The EEPROM allows parameters and programs to be saved in non-volatile memory
upon power down.
Motor Interface
For each axis, a GL-1800 custom gate array performs quadrature decoding of the encoders at up to 8
MHz, generates the +/-10 Volt analog signal (16 Bit DAC) for input to a servo amplifier, and
generates step and direction signal for step motor drivers.
Communication
Communication to the DMC-1500 is via two separately addressable RS232 ports. The ports may also
be configured by the factory for RS422. The serial ports may be daisy-chained to other DMC-1500
controllers.
General I/O
The DMC-1500 provides interface circuitry for eight optoisolated inputs, eight general outputs and
seven analog inputs (12 Bit ADC with option for 16 Bit ADC).
An auxiliary board, the DB-15072 provides interface to up to three OPTO 22 racks with 24 I/O
modules each. 24 bits can be configured for interface to output or input modules and the remaining 48
for input modules.
1580
Controllers with 5 or more axes provide 24 inputs and 16 outputs.
System Elements
As shown in Fig. 1.2, the DMC-1500 is part of a motion control system which includes amplifiers,
motors and encoders. These elements are described below
