5 Start Up
 Mechanical Installation and Wiring
Install the mechanical equipment and the hydraulic valve as described in the manufacturers
documentation. L1000H drives are designed to work with EV4 valves made by Blain Hydrau-
lics GmbH, Heilbronn, GERMANY.
 Power On
Before turning on the power supply,
• Make sure all wires are connected properly.
• Make sure no screws, loose wire ends or tools are left in the drive.
• After turning the power on, the drive mode display should appear and no fault or alarm
should be displayed.
 Motor Rotation Direction Setup
Depending on the elevator configuration it might be necessary to change the motor direction
in order to have the pump producing oil flow in up direction when the Run command is
given to the drive. Do the following to check the motor rotation direction and set parameter
b1-14 accordingly.
• With default setting of b1-14 = 0, the drive puts out voltage in U-V-W phase sequence
when a Run command is input. Check the motor rotation with this phase sequence (for
most motors clockwise seen from the shaft side). Disconnect the motor from the pump if
possible or set a slow speed which will not cause problems to the pump while giving the
Run command.
• If the pump flow is correct with a U-V-W sequence, keep parameter b1-14 set to 0.
• If the pump flow is incorrect with a U-V-W sequence, set parameter b1-14 to 1.
 Auto-Tuning (T1-)
Auto-Tuning automatically sets up the motor data relevant drive parameters. Two different
modes are supported.
Tuning Mode
Rotational
Auto-Tuning
Terminal resistance tuning
Never touch the motor until the Auto-Tuning is finished. Even thought the motor may not be
rotating when Auto-Tuning, voltage is still applied to the motor during the tuning process.
EN 20
Parameter
The motor must be able to rotate without load during the tuning
T1-01 = 0
process in order to achieve a high accuracy.
T1-01 = 2 Perform if the motor cable is long or if the cable has been changed.
