Z12A Series DESCRIPTION: The Z12A Series PWM servo amplifiers are designed to drive brush-type 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 analog +/-10V output. These servo amplifiers require only a single unregulated isolated DC power supply. SPECIFICATIONS: MODELS POWER STAGE SPECIFICATIONS Z6A6 Z12A8 16 – 60 VDC 16 – 80 VDC PEAK CURRENT (2 sec. max., internally limited) ±6A ± 12 A MAX....

Z12A 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. Please note that JE1 is a very small SMT jumper. Only qualified technicians are recommended to perform this modification. The product warranty will be affected by poor quality modifications. JE1 INSTALLED JE1: INHIBIT LEVEL (P1-5) NOT INSTALLED LOW to Inhibit LOW to Enable MOUNTING CARDS: With its vertical pin...
