SHA with Integrated Servo Drive
The SHA-IDT Series is a family of compact actuators that deliver high torque with exceptional accuracy and repeatability. These hollow shaft servo actuators feature Harmonic Drive® precision strain wave gears combined with a brushless servomotor, a brake, two magnetic absolute encoders and an integrated Servo Drive with CANopen® Communication. This revolutionary product eliminates the need for an external servo drive and greatly simplifies cabling yet delivers high-positional accuracy and torsional stiffness in a compact housing.
Key Features:
• Actuator + Integrated Servo Drive with CANopen® Communication
• 48VDC Supply Voltage
• Single Cable with only 4 conductors is needed:
CANH, CANL, +48VDC, 0VDC
• Zero Backlash Harmonic Drive® Gearing
• Panel Mount Connectors with radial and axial options
• Dual Absolute Encoders
• Output Sensing Encoder: 16 bit resolution (65,536 cpr)
• Input Sensing Encoder: 17 bit resolution (131,072 cpr)
• Control Modes: Torque, Velocity, Position, CSP, CSV, CST
• Harmonic Drive® HDL Software
Options:
• 4 I/O
• 2 NPN or 2 PNP Opto-Isolated Digital Inputs
• 2 Programmable Analog/Digital Inputs or Open Drain Outputs
• Motor Torque Off (MTO): When either or both of the 2 MTO inputs are low, PWM outputs to the motor are inactive and current to the motor will not be possible. Control power remains active.
• Flex-rated cables with sealed connectors available

- Value after temperature rise and saturation when the 320x320x16 [mm] aluminum heatsink is installed.
- Value of phase induced voltage constant multiplied by 3.
- For testing conditions, refer to [1-12 Shock resistance] (P1-41) and [1-13 Resistance to vibration] (P1-42) of SHA manual. Motor operation is not guaranteed in applications where vibrations and impacts are continuously applied for a long period of time.
- For details. refer to [3-3 Location and installation] (P3-6) of SHA manual.
