4.6 Setup Procedure for Elevator Applications
134 YASKAWA ELECTRIC SIEP YAIL1E 01A YASKAWA AC Drive L1000E Technical Manual
• Use a battery with a voltage higher than 250 Vdc for 200 V class drives or 500 Vdc for 400 V class drives and connect
it to the control power supply input (CN19). Alternatively use a 24 Vdc battery and an optional 24 V Backup Power
Supply Unit.
• Enable Light Load Direction Search (S4-01 = 1).
■ Using Separate Batteries for DC Bus and Control Power Supply, DC Bus Battery under 250
Vdc (500 Vdc)
Follow these instructions when using separate batteries for Rescue Operation with the battery for the DC bus having a
lower voltage than 250 Vdc for 200 V class drives and 500 Vdc for 400V class drives.
Wiring
Follow the wiring diagram shown in Figure 4.26 . When connecting the battery for the control power supply to the
L1000E, use the 1.1 m cable packaged with the product. The connector cover must first be removed in order to access
connection port CN19 for the battery. Refer to
Connecting the Drive and Battery on page 137 for details.
