Main circuit AC input power. For single-phase operation on smaller models (under 1.5 kW), use terminals L1 and L2 only.
: DC Bus connection terminals, utilized for external DC link reactors or shared DC bus layouts. B1, B2 : Dynamic braking resistor integration points. Control Circuit Terminal Blocks
Set the allowable stroke limits to prevent the machine from striking mechanical hard stops.
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) .
The Yaskawa K7 manual is a detailed guide that provides information on the installation, operation, and maintenance of the Yaskawa K7 servo drive. In this post, we will cover the key aspects of the manual, including its contents, technical specifications, and troubleshooting tips. yaskawa k7 manual
Yaskawa Varispeed G7/K7 Instruction Manual for installation and safety.
Do not conduct a megger voltage withstand test on the control terminals of the drive, as this will destroy the internal logic circuitry. 2. Product Lineup and Model Identification
: A reference for alarm codes and corrective actions to take when the drive or controller stops due to faults. Key Specifications (K7 Series)
: Instructions for using the Digital Operator (keypad) to program user constants, set I/O parameters, and handle error codes like "I/O PARA Error". Main circuit AC input power
Since "K7" is not a current flagship model number for Yaskawa inverters (drives), this write-up addresses the two most likely scenarios: the ** legacy K7 Series Hydraulic Servo Controllers** (often used in injection molding machines) and a possible confusion with the popular general-purpose drives.
Ensure the motor frame is grounded directly to the drive’s ground terminal. Ensure the CN2 encoder shield cable clip is properly bonded to the metal casing of the connector.
Best for initial drive/motor sizing and selecting part numbers.
Reduce mechanical friction, increase acceleration times, or upgrade to a higher torque motor. Encoder Communications Error B1, B2 : Dynamic braking resistor integration points
"CE" stands for "Communication Error." The drive is in network control mode (B1-01 = 3), but no valid Modbus signal is present. Change B1-01 to 0 (keypad) or 1 (terminals) to regain local control.
External resistor: Remove the B2-B3 jumper and wire the external resistor across B1 and B2. Never short-circuit B1 and B2. Motor and Feedback Connections
