Performance Specifications
SERVO Cycle Time:
(Settable with hardware jumpers)
•
Standard CPU - Minimum of 55 microseconds per axis controlled (110 usec for two axes; 440 usec
for eight axes)
•
Optional CPUs
•
Option 5A (40mHz): Minimum of 28 microseconds per axis controlled
•
Option 5B (60mHz): Minimum of 18 microseconds per axis controlled
SERVO Algorithm:
•
PID with velocity and acceleration feedforward and notch filter (5 to 500 Hz).
•
All gains with 24-bit resolution.
•
Dual encoder (motor and load) possible.
•
Optional ability to accept custom designed and installed servo algorithms for special applications.
•
Advanced seventh order pole-placement algorithm, 35 terms with autotuning capability (Option 6
required).
Phasing Update Time:
(Settable with hardware jumpers)
•
Minimum of 27 microseconds (1 axis)
•
Minimum of 110 microseconds (8 axes)
Phasing Algorithm:
•
Suitable for permanent magnet brushless motors, AC induction motors, switched reluctance servo
motors, microstepped stepping motors.
•
2, 3, or 4-phase motors, Y-wound, delta-wound, or electrically independent phases.
Block Execution Rate:
•
100-500 blocks (moves) per second with full trajectory calculation, depending upon particular
program conditions.
•
Approximately 250-1200 blocks (moves) per second possible at 40 MHz.
•
Higher rates possible with careful optimization, dependent on number of axes, servo cycle time, CPU
speed, and program complexity.
Velocity Range:
•
Range from 0.0001 to 20,000,000 counts/sec
•
Range from 0.0001 to 30,000,000 counts/sec (w/OPT 5A or 5B)
•
Digital phase-locked loop, crystal-controlled
Velocity Accuracy:
•
Long-term absolute accuracy
•
Standard Crystal: 0.005%
•
High accuracy Crystal: 0.001% (Option 8)
•
Short-term absolute accuracy - System-dependent; typically 0.2% to 1.0%
Position Range:
•
2 billion counts minimum (32 bits) with automatic rollover
