4.6 Setup Procedure for Elevator Applications
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
Table 4.13
.
When using a PM motor with an incremental PG encoder and a PG-X3 option card, always perform Initial Magnet Pole
Search Parameters Auto-Tuning (T2-01=3) with the normal power supply connected. The tuning function will prepare
the drive for Rescue Operation by automatically setting certain parameters. If the tuning ends with an “End8” to “End10”
fault, then rescue operation will require a battery or UPS that supplies the drive DC bus with at least 280 Vdc for 200 V
class drives and 560 Vdc for 400 V class drives. Alternatively utilize to an absolute PG encoder and a PG-E3 or PG-F3
option card.

■ Parameter Setup
Adjust drive parameters as described below when using Rescue Operation.
• Select the type o f 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 o f 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 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.
