Control Driver for Brushless Motors

Special Features

• This driver is uninfluenced by ambient variations like temperature because of full software servo.
• Synchronous Tracking Drive Circuit Controlling without pulse pool is possible.
• Stable Positioning Integral operation enables high precision stable positioning.
• Single Power Source Commercial regulator or battery can be applied because single DC power tailored for motor can be supplied.
• Multiplication Function of Encoder ×1, ×2, ×4 multiplications are selectable by internal setting.
• Protection Circuit Several Protection Circuits are installed to protect motor.

Special Features

• Usable for many different Coreless DC motors thanks to the wide range of power supply voltage: +12V to +50V. No need to prepare a complicated control power supply because of a single power supply.
• Encoder signal can be used for speed-feedback, in addition to DC tacho signal.
• Respond to the encoder's max. frequency of 500kH with use of the high-speed F/ V converter (max. frequency: frequency of Phase A or Phase B. Internal operation: runs at frequency of 2Mz after being multiplied by 4.
• Usable for many different Coreless DC motors with use of the output- stage choke coil equipped as standard.
• Prevent uncontrolled rotation with the encoder's detector of wire disconnection at the speed-control mode.
• Reduce speed fluctuation caused by load change, with use of IR correction at the voltage-control mode.
