3.8 Does the iS7 frequency inverter have vector control?
The iS7 frequency inverter has vector control and a few extras:
Conformity with global standards
UL Plenum rated
(American Standard for Fire Protection)
Marine approval (BV; ABS; DNV certificate)
IP54 available from 0.75-22kW
Integrated brake chopper
Dynamic transistor for brake control as a standard
A thermistor or PTC thermistor as external motor protection
What vector control means:
The frequency inverter measures the speed and compares it with the setpoint speed.
If the difference is too great, it increases the voltage and thus the current flow.
