Features

of SMA7029M. The basic function pins are compatible with those of SMA7029M. Connect TTL or similar to the SYNC terminals and switch the SYNC terminal level high or low. When the motor is not running, set the TTL signal high (SYNC terminal voltage: 4 V or more) to make chopping synchronous. When the motor is running, set the TTL signal low (SYNC terminal voltage: 0.8 V or less) to make chopping asynchronous. If chopping is set to synchronous when the motor is running, the motor torque deteriorat.
