ZBDC12A Series DESCRIPTION: The ZBDC12A Series PWM servo amplifiers are designed to drive brushless DC motors at a high switching frequency. They are fully protected against over-voltage, over-current, over-heating and short-circuit. A single digital output indicates operating status. All models interface with digital controllers that have digital PWM output. The PWM IN duty cycle determines the output current and DIR input determines the direction of rotation. These servo amplifiers require only a single unregulated isolated DC power supply. SPECIFICATIONS: MODELS POWER STAGE...

ZBDC12A Series JUMPER SETTINGS: Pin P1-5 can be used to enable or disable the power output to the motor. The default logic level to disable this amplifier is a LOW signal at P1-5. With the jumper JE1 removed, the amplifier will be disabled until a LOW signal is applied to P1-5. JE2 is a jumper to select between a 120-degree phased motor and a 60-degree phased motor. The default setting is 120-degree commutation phasing. Removing the JE2 jumper will change the setting to 60-degree. Please note that JE1 and JE2 are very small SMT jumpers. Only qualified technicians are recommended to perform...
