Setup

Switches and Potentiometers (Some models have fixed settings)

Motors

All models compatible with - Brushless, Brushed, Rotary, Voice Coil, Inductive Load.

Command Source(s)

±10V Analog: Drives accept single ended and differential signals.

PWM & Direction (Torque Mode) - Products with 'DDC' and 'BDC' in the model number - The PWM signal is converted to an analog voltage in the drive. This voltage is used as the command signal into the current loop just like our other current mode products. This means the user does not have direct control of the output duty-cycle or switching frequency. Instead, the user's input duty-cycle controls the drive's output current.

Power

DC Voltage Range: 10 - 175 VDC

Feedback

Tachometer - Scaled to 60V max.

Hall Sensors - Required for commutation of 3Φ brushless motors. ADVANCED Motion Controls servo drives are compatible with 120° and 60° Hall spacing. For selected drives the Hall sensors can also be used for velocity feedback in Hall Velocity mode.

TTL Encoder - 5V incremental encoder feedback. On our analog servo drives, encoders are used for velocity feedback in Encoder Velocity mode.

Mode

Torque - The input command controls the output current (torque). The servo drive will adjust to disturbances and maintain the commanded current. This is the suggested mode if an external controller is used which can close the velocity or position loops.

Duty Cycle (open loop) - The input command controls the output PWM duty cycle. This mode is used in simple applications where velocity feedback is not available and precise velocity control is not necessary. Similar to voltage mode but not as precise.

Hall Velocity† - The input command controls the motor velocity. This mode uses the motor's Hall sensors for velocity feedback. Due to the low resolution of the Hall sensors, this mode is not recommended for low speed applications. In high speed applications this mode can provide excellent performance.

Velocity† - The input command controls the motor velocity. Drives use high resolution feedback on the motor or load to close the velocity loop.

Additional Options

Additional Options are available for some models - see individual datasheet in the Part Numbering Information section. If the requested option is not in our current product offering it can be made available with sufficient volume. Contact Us for availability.

Indicate the option at the end of the part number. Ex AZBE12A8-INV.

-ANP (Analog Position Loop Mode) - Allows the drive to close the position loop using a potentiometer for feedback.

-INV (Inverted Inhibits) - Pull low to enable / open to disable. This is the inherently safe method to inhibit since a break in the control line will cause the drive to inhibit.
