Product Description:
The Danfoss 178B4558 Drive supports three phase 380 – 480 V input with efficient motor control. It is designed with an IP20 enclosure and provides flexibility with precision in automation. The drive is suitable for applications requiring stable speed and torque performance.
The 178B4558 drive operates with an input phase to ground voltage of 300 V for insulation safety. It draws approximately 14.9 A input current. The device delivers an output current near 16.0 A. Its apparent power rating is about 11.1 kVA. It can produce output frequencies from 0 to 1000 Hz that allows wide motor speed range. The maximum ambient operating temperature is + 45 °C (113 °F). The control modes supported by this model include open loop (scalar) control for simple speed applications and closed loop vector control for more accurate regulation. The Automatic Motor Tuning (AMT) measures stator resistance without rotating the shaft that enhances matching and tuning. The programmable ramp times provide smooth acceleration and deceleration. The ramp up and quick stop ramp down times are both configurable from 0.02 to 3600 seconds. These features help protect mechanical systems and reduce load stress. The drive includes motor overload alarms and thermistor based (PTC) thermal protection. The current limit and overcurrent alarms protect against abnormal load conditions including transient peaks up to 200 % of rated current.
The 178B4558 drive from AKD series includes a built-in Local Control Panel (LCP). This panel features a six digit LED display for real-time parameter monitoring and diagnostics. The navigation is simplified with dedicated keys for data entry, parameter selection and quick menu access. The quick menu allows up to 20 user defined parameters for easy access to frequently used settings. These interface tools enhance on-site setup and maintenance efficiency.
Frequently Asked Questions about 178B4558:
Q: What user interface features does the 178B4558 drive provide for local diagnostics and quick setup?
A: The built-in Local Control Panel (LCP) includes a six-digit LED display and dedicated navigation keys. It also offers a customizable quick menu with up to 20 user-defined parameters.
Q: How does the 178B4558 drive handle high-frequency motor control in variable-speed industrial systems?
A: It delivers output frequencies from 0 to 1000 Hz, allowing for a wide speed control range. This supports precise regulation in high-speed or specialized motor applications.
Q: What startup and stop behavior can be configured on the 178B4558 drive for mechanical protection?
A: Its ramp-up and quick-stop ramp-down times are programmable from 0.02 to 3600 seconds. This enables smooth transitions that reduce stress on mechanical components during acceleration and deceleration.
Q: How does the Danfoss 178B4558 drive support efficient motor matching and tuning during commissioning?
A: It features Automatic Motor Tuning (AMT) that measures stator resistance without rotating the shaft. This allows accurate tuning and improved drive-to-motor alignment in fixed load setups.
Q: How does the 178B4558 drive protect the motor during overload or transient fault conditions?
A: It includes thermal protection via PTC thermistors and configurable current limits. It can handle peaks up to 200% of rated current, triggering overload and overcurrent alarms when needed.
