■ Drive Power Supply for Rescue Operation
There are various methods of supplying power to the drive for rescue operation. Independent of the chosen
method, the voltage in the DC bus of the drive and the voltage supplied to the drive control circuit must meet the
specifications provided in the following table.
The DC bus voltage can either be supplied by a battery connected to the DC bus terminals of the drive or by a
UPS connected to drive terminals L1 and L2. The control circuit voltage is supplied directly from the drive’s DC
bus.
When using a single-phase AC power supply for rescue operation such as a single-phase UPS, the ripple in the
DC bus voltage will be higher than with a three-phase or battery supply. Make sure that the DC bus voltage never
falls below the minimum value listed in the following table.
Table 4.8 Power Supply Ratings for Rescue Operation
Timing Zone Description Control Circuit Voltage
Induction Motor
200 V class drives: 115 to 300 Vdc
400 V class drives: 230 to 600 Vdc
Same as DC Bus Voltage.
■ 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 should be detected, also set up parameters S4-12 and S4-13. Measure the
DC bus voltage during operation with 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 to select if light load direction search should be automatically performed when
Rescue Operation is started and to configure the light load search function.
■ 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 or 400 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 or 500 Vdc for 400 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 or 500 Vdc for 400 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. 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. 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. Failure to comply can result in death or serious injury
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: Equipment Hazard. Do not use the Rescue Operation feature for extended periods. Failure to comply can result in
drive heat sink overtemperature alarms (oH).
■ Using a Single-Phase 230 Vac UPS (Uninterruptable Power Supply)
Follow the instructions when using a single-phase 230 V UPS for Rescue Operation. A 230 V UPS can be used
for both 200 V and 400 V class drives.
