  • Cooling Capacity and Pressure Drop: Performance curves for cooling capacity and pressure drop using mineral oil and a 50% water glycol mix are provided.
Technical Features
  • Electrical Specifications: Operating supply voltage ranges from 16.0 to 32.0 V, with a maximum speed supply voltage of 26.0 to 32.0 V. The ambient temperature range is -40 to +110°C.
  • Protection Features: Includes load dump protection, reverse polarity protection, and compliance with standards like ECE reg. 10-04 and RoHS.
  • Connector Details: Utilizes a YAZAKI HYBRID connector compliant with USCAR-2 standards.
Control and Interface
  • Drive Modes: Operates in quiescent, active, run, and failure modes, controlled via PWM and analogue inputs.
  • Interface Options: Eight interface modes are described, including on/off control and mixed analogue/digital control.
  • Failure Handling: Strategies for handling failures like rotor lock, overload, and overheating are outlined, with automatic recovery attempts.
Additional Features
  • Transfer Functions: Describes the relationship between drive speed and control inputs, focusing on PWM and analogue signal processing.
  • Software Functions: Details on drive response to control inputs and mode transitions.
Interface Modes
  • Mode 6: Controlled by a low current enable input, entering quiescent current mode when high and operating at requested speed when low.
  • Mode 7: Similar to Mode 6 but uses a PWM signal for speed control, determined by the PWM duty cycle.
  • Mode 8: Allows mixed control with digital PWM or analogue input, prioritizing the digital PWM signal.
Technical Features
  • Supply voltage range: 9 - 32 V DC
