DSP technology widens prospects for stepper drives
This article shows how the latest DSP (digital signal processing) technology has been exploited in a new generation of direct digitally controlled stepper drives.
Both binary and decimal resolutions are available.
Designed around advanced surface-mount ASIC technology, the compact units use rugged MOSFET power stages and a compact high-efficiency heatsink to obtain continuous operation from the Euromodule 3U x 160mm format drive, with natural free air convection cooling normally being sufficient.
A standard module width of 9HP (1.8in) allows as many as eight drives plus power supply to be housed in one 19in wide rack.
Winding current can be easily set to match the motor characteristics to the load while the motor is running, either by a rotary switch on the front panel or a resistor connected to the drive backplane.
Five current ranges from 0.5 to 16.5A are available.
In addition, the drive has a boost input which increases current output by 30%, a useful feature for providing rapid acceleration and one that can also be used continuously.
A feature known as comprehensive dynamic protection (CDP) monitors the drive's dynamic environment and reacts within 5us to protect itself against all motor winding faults, including short-circuit to winding, short-circuit to ground and low-inductance winding.
In addition, there is protection against irregular motor supply voltage, low logic supply and overtemperature conditions.
Reliability is ensured by the use of conservatively rated components combined with thorough production testing of all units under simulated fault conditions and for correct thermal performance.
As a result, each DM drive provides a long life of trouble-free operation, even during adverse operating conditions.
