Yaskawa K7 Manual May 2026
Manual answer: Set parameter A1-05 = 1110 for a 2-wire default, or A1-05 = 2220 for 3-wire default. Then cycle power. Warning: This resets all parameters to fan/pump defaults, not general-purpose.

The Yaskawa Varispeed K7 (CIMR-K7) is a legacy industrial AC drive (Variable Frequency Drive) designed for advanced motor control . Because it is a legacy/discontinued module, sourcing an exact step-by-step operator's manual directly from the current web portal can be difficult, as many users are steered toward newer replacements or the closely related Yaskawa Varispeed G7 .
Below is an organized technical overview and report acting as a reference guide for the Yaskawa K7 drive based on standard manufacturer operations. 📋 Yaskawa Varispeed K7 Overview
Device Type: 3-Phase AC Variable Frequency Drive (Inverter) .
Input Voltage: Typically 380V to 480V AC (400V Class), 50/60 Hz . Manual answer: Set parameter A1-05 = 1110 for
Output Specs: 0 to 480V AC, with an adjustable output frequency range up to 120Hz Common Models: For instance, the CIMR-K7H4015 is rated for 15 kW (approximately 20 HP) .
Origin Note: Some K7 units specifically carry "Made in UK" identifiers on their chassis plates . ⚡ Safety & Installation Guidelines
Refer to standard high-voltage industrial precautions before handling any physical hardware:
High Voltage Warning: Do not connect or disconnect any wiring while the main power supply is active .
Capacitor Discharge: After turning off the input power, wait a minimum of 5 to 10 minutes . Verify that the internal charge lamp has completely turned off and check DC bus voltage levels before removing protective covers .
Short Circuit Prevention: Never connect AC main power lines directly to the output terminals (
) . Doing so will immediately destroy the internal inverter components . The Yaskawa K7 manual repeatedly emphasizes five critical
Mounting: Always mount the heavy chassis on a non-combustible material (such as a structural metal plate) to avoid heat-related fire hazards . ⌨️ Digital Operator & Quick Setup
Yaskawa drives typically feature a 5-button or multi-key digital operator keypad with a display and localized status LEDs : Varispeed G7 - Instruction Manual
The Yaskawa K7 manual repeatedly emphasizes five critical safety rules. Ignoring them can cause injury or drive destruction:
The K7 was one of the first drives to integrate Mechatrolink-II. The manual’s appendix provides the exact register mapping (MEMOBUS) for controlling speed, torque, and reading status via cyclic data.
For over a century, Yaskawa has been a titan in the motion control and drive industry. Among their extensive product lineup, the Yaskawa K7 series (often referred to as the UAK7 or simply the K7 Drive) holds a special place for applications requiring high performance and rugged reliability. Whether you are a maintenance technician, a controls engineer, or a plant manager, the Yaskawa K7 Manual is the single most critical document you need for installation, programming, and diagnostics.
In this long-form guide, we will break down exactly what you will find inside the Yaskawa K7 manual, how to use it to solve common faults, where to find official PDFs, and the advanced parameters that unlock the drive’s full potential.
This section contains strict guidelines on clearances, cooling, and terminal torques. A common mistake the manual warns against is placing control wiring alongside high-power cables. The manual provides specific diagrams for:
The K7 manual dedicates a full chapter to the operator panel. Unlike newer LCD screens, the K7 often uses a 7-segment LED display. The manual teaches you how to:
