Variable frequency Drives (VFD)

We are one of the leading suppliers of Hitachi make Variable Frequency Drives in the market.

• Powerful, compact drives with application features to
• address a wide-range of applications.
• Capability to supply AC or DC input in the drive for
• standalone configurations and common DC bus
• configurations.
• For multi-drive applications, powerful rectifier-based DC
• supply units and full-regenerative IGBT based DC supply
• units (400 KW and above) for use with these drives are
• available.
• Very high starting torque capabilities to meet
• application requirements of many demanding
• applications (200 % at 0.3 Hz. motor RPM).
• Special 0 Hz domain sensorless vector control algorithm
• to provide very high torque at 0 Hz. Motor speed (150%
• at 0 Hz. motor RPM).
• Precise control of speed and torque of motor using
• sensorless vector control, close-loop vector control and
• powerful V/F control modes.
• Powerful position control functions using external
• encoders and pulse train inputs.
• Trip-less functioning during acceleration and
• deceleration
• In-built RS-485 Modbus communications interface
