Product Description:

The SC723 Servo Controller from Pacific Scientific is used to control electric motors in industrial motion systems. The firm has engineered solutions to support consistent functioning across a wide range of industrial automation tasks.

The SC723 servo controller has a torque and velocity controller using a resolver-based feedback system with encoder emulation. It interprets analog or digital command signals to regulate velocity output to the connected motor. It is rated at a continuous current consumption level of 7.5 A and a peak output of 15 A which helps in supporting moderate power motor control tasks across varied industrial environments. The controller interfaces smoothly with drives utilizing resolver feedback by allowing stable and responsive performance under load variation. It contains a designation of customization and suffix by including the module designator is factory-assigned. This will ensure there is no manual creation and variation of sets of programming and setup. It is a small design with low space requirements and it is EMC marked which proves that it is safe from nearby distortion of devices or drives.

The SC723 controller has the CE marking indicating European standards compliance and is UL recognized offering assurances of safety in the North American markets. Its controller facilitates installations at altitudes of up to 1000 meters above sea level and can be used in altitude mid-level operation environments. It comes with pre-set configuration and other factory settings meaning that it is always compatible with systems. The unit features onboard status LEDs for power, fault and run indications which aid in basic diagnostics without external equipment. It also uses DIN rail configurations for the simplest installation in industries.

Frequently Asked Questions about SC723:

Q: What mounting options are available for the SC723 unit?

A: The SC723 is panel-mountable and fits standard enclosures. Optional adapters allow DIN-rail installation in compact automation systems.

Q: What is the function of the SC723's internal fault retry logic?

A: It automatically resets and attempts recovery from transient faults, improving uptime in industrial environments.

Q: What input voltage does the SC723 support for power and control?

A: The controller accepts 120/240 VAC single or three-phase for motor power, and 90–264 VAC single-phase for logic supply.

Q: What happens if the SC723 exceeds its thermal limits during operation?

A: It enters thermal shutdown to protect internal electronics and prevents drive damage from overheating conditions.

Q: Why is the SC723 equipped with resolver feedback instead of a direct encoder?

A: Resolver offers durability in harsh environments. SC723 processes resolver signals while generating encoder-compatible output for system integration.


Internal Product Review

  • ‘‘The SC723 controller from Pacific Scientific's SC720 series operates on 240V three-phase power with CE and UL compliance. Its resolver-based feedback and 15A peak output ensure performance under high dynamic loads. It uses reliable encoder emulation that allows integration into systems not originally designed for resolver input.’’
