1.1 Q-Drive Characteristics
The main characteristics of the Q-Drive servo-amplifiers are as follows:
• Digital servo-amplifier with analogue speed command +/- 10V, for Brushless
motor with resolver.
• Utilises a 16 bit DSP (Digital Signal Processor)
• Compact unit for connection to 3 phase power supply with built-in braking
module.
• Double Eurocard Format using Surface Mount Technology (SMD).
• Completely programmable by a multi-drop RS422 or direct RS 232 serial link.
• Sinusoidal current output assures smooth torque and optimum performance at
low speed.
• Power and command circuits are optically isolated from each other.
• Protections and ruggedness for use in severe conditions.
• Easy to use external connections including two part connectors for resolver
input and encoder output.
• Simulated incremental encoder output with adjustable resolution to 1024 ppr
and adjustable marker pulse. Differential line driver outputs.
• 7 segment status indicator for diagnostic display.
• Short-circuit protected output stage.
• I

t protection.
• Detection of resolver fault, motor overheating.
• Velocity or current regulation.
• Auxiliary voltages are produced within the drive, no external power supply
required.
• Drive can be enabled using an optional opto-coupled input or using a volt free
contact.
• Motor connections are constantly monitored.
