IronHorse GSD8 Series DC Drives General Information
Introduction
The GSD8 series DC drives are compact, microprocessor based motor controllers capable of factory or
field configurations for a variety of industrial applications. GSD8 DC drives make use of either a pulse
accumulation algorithm (GSD8-240-5C drive) or a velocity PID algorithm (all other GSD8 drives) that
can be easily configured for operation as a speed controller, time-based process controller, or follower
drive in a master-slave application. Using modular design techniques, the GSD8 drives are perfect for
applications that require specialized I/O. GSD8 DC drives are ideal for applications such as:
•
Water and Waste Water Treatment Systems
•
Conveyor Oven Controllers
•
Synchronized Conveyor Lines
The GSD8’s durable aluminum housings can be easily mounted in a panel or control cabinet. The
pluggable terminal block allows for easier wiring and quick replacement without the need to remove
and reattach wiring.
Standard Features
•
Microprocessor-based design combines the ultimate in responsiveness and accuracy in one package
•
Digital closed-loop algorithm ensures long-term accuracy of ± 1/2 RPM of set speed or equivalent
•
Non-volatile memory stores adjustable parameters even when power has been removed
•
Factory or field programmable via front-panel keypad
•
Adjustable parameters include min, max, accel, decel, display options, alarm options, etc.
•
Internal program-enable jumper selectively prevents tampering with unit’s configuration
•
Universal power supply accepts line voltages inputs from 85-265 VAC @ 50-60 Hz without switches or
jumpers. The unit automatically adjusts as needed.
•
Transient voltage protection prolongs unit’s life in harsh industrial environments
•
Compatible with a variety of signal input types including: Hall-Effect Pickups, Photoelectric, TTL, etc.
NOTE: Open collector devices must be capable of sinking 3mA. Encoder signal specifications are
incremental, 5-24 VDC, open collector/sinking source.
•
Self-contained power supply for external sensor, limited to 5V @ 50mA
•
Programmable alarm output with Form C contacts rated to 250VAC @ 5A
•
Flexible user inputs support inhibit, emergency stop, and jog functionality
•
Standard 1/8 DIN panel mounting for the GSD8-240-5C and GSD8-240-5D
•
Standard 1/4 DIN panel mounting for the GSD240-10C-D
•
Large 4 digit, 1/2” LED display
•
G.E. Lexan membrane and gasket (which are included) meet NEMA 4X standards when used with
NEMA 4X enclosures
•
European terminal block
•
UL Listed #E333109, RoHS
•
Wide operating ambient temperature range of -10
°
C to 45
°
C (14
°
F to 113
°
F)
•
Multiple operating modes including:
•
Master, Rate Mode – Controls in rate unit such as RPM, gallons per minute, etc.
•
Master, Time Mode – Controls in time unit such as HH:MM, MM:SS, SS:TT, or other unit
•
Follower Mode – Controls in percentage of master rate. This mode allows the GSD8 drive to
precisely follow the actions of a master process without any long-term loss of position
Carefully check the DC Drive for shipping damage. Report any damage to the carrier immediately.
Do not attempt to operate the drive if visible damage is evident to either the circuit or to the
electronic components.
