Delta VFD17AME43AFSAA: Compact variable frequency drive for industrial drives

The VFD17AME43AFSAA variable frequency drive from the ME300 series is designed to control three-phase motors in industrial applications. The ME300 series combines a compact design with vector control, integrated safety and communication functions, and support for both induction motors and permanent magnet motors.

The VFD17AME43AFSAA model is designed for a 380–480 V AC three-phase power supply and motors up to 7.5 kW / 10 HP. The rated output current in Heavy Duty mode is 17 A. This variant includes an integrated EMC filter and the STO (Safe Torque Off) function.

Technical specification

High-performance motor control

The ME300 supports asynchronous (IM) motors as well as synchronous permanent magnet motors (IPM and SPM), allowing a single drive type to be used across various drive configurations. It offers V/F and SVC control methods and supports up to two independent motor parameter sets.

For demanding applications, the drive provides high overload capability; in Heavy Duty mode, it handles 150% of the rated current for 60 seconds and 200% for 3 seconds. Additionally, the ME300 includes features such as rapid deceleration, motor speed search, PID control, multi-step speed control, and other drive management functions.

Safety and reliability

The AFSAA variant combines an integrated EMC filter with the STO (Safe Torque Off) safety function. STO meets requirements including ISO 13849-1 Category 3 PL d and EN 61508 SIL2. This function enables the safe removal of motor torque and can simplify the design of the machine’s safety circuit.

Additionally, the ME300 series boards feature a protective coating compliant with IEC 60721-3-3, enhancing resistance to moisture, corrosion, and dust.

Easy integration into the machine

The ME300 comes standard with RS-485 (Modbus protocol), allowing for easy integration with a PLC or other control system. An integrated braking chopper enables higher braking torque when an external braking resistor is connected. The drive also supports pulse/PWM input and a common DC bus.

Installation is simplified by screwless spring-clamp control terminals and application-specific parameter groups—for example, for pumps, fans, compressors, or conveyors.

Areas of application

The Delta ME300 series is suitable for a wide range of industrial applications, particularly:

• conveyor systems
• fans
• single and multiple pumps
• packaging machines
• textile machinery
• woodworking machinery

For the ME300 pumps, it offers integrated PID control, constant pressure mode, multi-pump alternation, leak detection, sleep mode, and dry-run protection.

Why choose the Delta VFD17AME43AFSAA?

The Delta VFD17AME43AFSAA is an ideal choice for controlling motors up to 7.5 kW when you require a compact design, STO safety functionality, an integrated EMC filter, and Modbus industrial communication without the need for additional modules. Support for IM, IPM, and SPM motors, high overload capability, and a built-in braking chopper allow a single drive to be used across a wide range of machinery applications.
