The FR-A540 range, with 15 models from 1.5kW to
55kW, is a new generation of motor drives for the
global market, designed for a 10 year working life
without having to be taken out of service.
A500 delivers a major leap in dynamic
performance to 120:1 speed control range in drive
mode and 25:1 in regenerative braking mode without
encoder feedback. At low speeds, A500 delivers
unrivalled smoothness with torque ripple under 5
per cent at 3Hz. Used with a motor fitted with
encoder feedback, speed control range extends to
1000:1, speed variation range falls to under 0.02
per cent and the A500 can deliver short term zero
speed holding torque of 150 per cent. On-Line Auto
Tuning (OLAT) continuously re-optimises control as
the motor temperature or other parameters change -
and Soft PWM control greatly reduces acoustic
noise.
- Advanced Magnetic Flux Vector Control
- High Response Current Limit
- Simple Maintenance
- Soft-PWM control
- International Standards Compliance
- RS-485 serial communication ready
