Geo Drives

The Geo Drive family of servo amplifiers provides many new capabilities for users. This

family of 1 and 2-axis 3-phase amplifiers supports a wide variety of motors, power ranges,

and interfaces. Geo Drives operate directly off the power main (100 to 480 VAC) for motor

power and an external power supply of +24 volts DC for logic power.

Geo Direct PWM Drives

The direct PWM Interface version accepts direct PWM transistor control signals from the

controller, while providing digital phase current feedback and drive status to the controller

for closed-loop operation. Interface to the direct PWM drive amplifier is through a standard

36-pin Mini-D style cable, compatible with most power-block drives. The drive performs no

control functions but has protection features. System installation and maintenance is reduced

because there is less wiring (position feedback or I/O are not connected to the drive) and

programming or variables are not set in the drive.

• Versatile input voltage range: 100-480 50/60 Hz

• Dual-Axis configurations are economical and save panel space and installation wiring

• Centralized Control: Programming is done in the PMAC eliminating redundant CPU issues

• Complete Protection: Over Voltage, Under Voltage, Over Temperature, PWM Frequency

Limit, Minimum dead time, Motor Over Temperature, Short Circuit, Over Current

• Integrated Bus Power Supply Including Shunt Regulator (external resistor required)

• Full ratings to 45¯C Ambient

• Wide Power Range

Geo MACRO Drives

The Geo MACRO Drive interfaces to the controller through the fiber-optic MACRO 125

Mbit/sec ring, accepting numerical command values and returning numerical feedback

values over the ring. Normal ring operation allows a choice of sending PWM commands,

torque commands, velocity commands or position commands. The Geo MACRO Drive

accepts many types of motor position feedback for loop control and feedback to the master

controller. I/O can be transmitted on the ring for high level integration such as limits, home

and general-purpose I/O points. The Geo MACRO Drives are typically commanded by

either a PMAC2 Ultralite board, UMAC or QMAC System, providing a convenient solution

for distributed or centralized control using a fiber optics connection.

• 1 or 2 standard encoder input channels: A/B quad or sinusoidal with1024x interpolation

• General-purpose I/O connections: 4 In, 4 Out, 24 VDC

• RS-232, USB or Ethernet port for communication drive configuration

• Single digit status display and six LEDs for status information

• Supports resolver and absolute encoder feedback

Geo Analog Drives

The Geo Analog Drive accepts a +/-10V analog command into a 16-bit A/D converter, representing either a

velocity or torque command. It can accept several styles of position feedback (required for commutation of a

brushless motor), including single or dual quadrature or sinusoidal encoders (built-in interpolator x1024), resolvers

and absolute serial encoders (SSI, EnDat, Hiperface). Regardless of the feedback, position information passes back to

the controller as synthesized quadrature output. Options support Profibus, DeviceNet, USB and ethernet field buses.

Geo PMAC Drives

The Geo PMAC Drive is a standalone single-axis controller/drive with stored-program capability. It contains a Micro

PMAC controller, providing full positioning and trajectory capabilities with synchronization to other drives and/or

external encoders. The Geo PMAC Drive accepts many types of position feedback, including single or dual quadrature

or sinusoidal encoders with interpolator, resolvers and absolute serial encoders (SSI, EnDat, Hiperface). It also provides

an interface for flags (limits and home) and general-purpose I/O points. An option supports a CANBus interface as

well as Profibus and DeviceNet Field Bus I/O. The MACRO ring can be used for high-speed communication.
