Parameter Setup
■
Adjust drive parameters as described below when using Rescue Operation.
• Select the type of Rescue Operation power supply for the drives main circuit in parameter S4-06.
• When using a UPS, set the UPS power value to parameter S4-07. Use parameter S4-08 to decide if the Rescue
Operation speed shall be limited automatically depending on the UPS power.
• If deterioration of the battery or UPS shall be detected, also set up parameters S4-12 and S4-13. Measure the DC bus
voltage during operation using the rescue power supply and set the measured value to parameter S4-12. Set the
deterioration detection level to parameter S4-13.
• Set parameters S4-01 to S4-04 if light load direction search shall be automatically performed when Rescue Operation is
started.
■ Wiring Examples
Switching the main power supply to a battery or UPS requires magnetic contactors that must be controlled by an external
controller. Wiring methods and the sequence used for the magnetic contactors depend on the application. This instruction
manual describes the following configurations:
• A single-phase, 230 V UPS is used as backup power supply for a 200 V, 400 V or 600 V class drive.
• Two separate batteries for the main power and control power supplies. Main power battery voltage is below 250 Vdc for
200 V class drives, 500 Vdc for 400 V class drives, or 720 Vdc for 600 V class drives.
• Two separate batteries. One is used for the main power supply, a second battery supplies the controller via an optional
24 V Backup Power Supply Unit.
• A single battery with minimum 250 Vdc for 200 V class drives, 500 Vdc for 400 V class drives, or 720 Vdc for 600 V
class drives is used for the main and control power supply.
Select the configuration that matches your application. Follow the corresponding instructions for wiring and drive
settings. For configurations not covered in the list above, contact your Yaskawa representative or our sales office directly
for consultation.
WARNING! Electrical Shock Hazard. Do not connect or disconnect wiring while the power is on. Never remove or install option cards or
attempt to replace the cooling fan while the drive is switched on. Make sure that the drive and all devices connected to the drive have
been shut off prior to performing and type of maintenance or wiring. After shutting off the power, wait for at least the amount of time
specified on the drive before touching any components or perform wiring. The internal capacitor remains charged even after the power
supply is turned off.
NOTICE: Be sure to thoroughly read the instructions for wiring and magnetic contactor sequence described in this section before
setting up the drive for Rescue Operation. Failure to follow these instructions can damage the drive.
NOTICE: Refrain from using Rescue Operation for extend periods of time. Rescue Operation uses a low DC bus voltage, which can
cause the cooling fan to shut off temporarily during Rescue Operation. Continuing to operate under these conditions can trigger an
overheat fault and damage the drive.
NOTICE: Install the inrush current suppression circuit outside the drive if the DC bus battery voltage is lower than 190 Vdc for 200 V.
NOTICE: Install the inrush current suppression circuit outside the drive if the DC bus battery voltage is lower than 190 Vdc for 200 V
class drives of models CIMR-LU20215 to 20415, 380 Vdc for 400 V class drives of models CIMR-LU40150 to 40605, and 500
Vdc for 600 V class drives of models CIMR-LU50099 to 50200. Failure to comply will cause the soft-charge bypass relay to remain
open and result in damage to the drive.
