Specification of Drive Functions
Devices of the series SD2S can operate with different drive functions depending on the
loaded drive software. The different drive functions support different motors and motor
measuring systems.
The available drive functions depend on the device type and device version.
▶
SERVO / VECTOR
For linear and rotary synchronous and asynchronous motors:
─
mean speeds (< 120,000 rpm)
─
high resolution measuring systems
─
high performance speed control
─
full control at low speeds and standstill
─
special feature SVC (sensorless vector control): sensorless operation (up to
120,000 rpm)
▶
VF ( V/f control)
For rotary asynchronous motor:
─
V/f PWM available for devices with fix DC link voltage
─
PWM: mean speeds (up to 120,000 rpm)
─
V/f characteristic curve for asynchronous motors
─
simple parameterization and unproblematic operation of motors
─
sensorless operation
(Optionally a measuring system for speed monitoring can be used to signal
the states “speed zero” and “reference value reached”.)
The following figure shows the speed ranges of the different drive functions:
