The following sections detail the set-up, programming and auto tuning in order to get the Elevator drive operational. Parameter settings can be made
through the simplified User Menu A or through the standard drive menu’s available Menu B through to Menu Z.
7.1 Operating mode
When the drive is first powered up, and prior to programming the parameters, the correct operating mode should be selected. The default operating
mode is RFC-S, selecting an alternative operating mode can be done as follows (a) Ensure the drive is disabled (b) Set Pr
mm00
= 1253 (c) Select
operating mode in
Drive Control Mode
(
B01
) (d) Press Reset button.
Table 7-1 Operating modes
When setting up a drive and where the current parameters are unknown, a drive default is recommended before starting. A default can be carried out
as follows:-
•
Ensure the drive is disabled
•
Set Pr
mm00
= Reset 50 Hz defaults or Pr
mm00
= 1233
•
Reset the drive.
7.2 Motor and Encoder data
In order for the drive to control the motor with a high level of control, both the motor nameplate data and position feedback details RFC-A, RFC-S)
need to be set-up in the following drive parameters and an autotune carried out. The default operating mode for the
E300 Advanced Elevator
drive is
RFC-S for gearless Elevator applications using a PM synchronous motor.
The drive must be set-up by a responsible person who is familiar with the systems operation and safety requirements to avoid a safety
hazard. Correct set-up must be carried out as detailed in this guide
to avoid the risk of death, serious injury or product damage.
Ensure that no damage or safety hazard could arise due to any unexpected motor starting. Ensure the drive is operated in accordance
with the systems safety requirements to avoid the risk of product damage and a safety hazard.
Where the maximum speed affects the safety of the machinery resulting in a safety hazard, additional independent over-speed protection
must be used to avoid the risk of product damage or a safety hazard.
The AC supply must be disconnected from the drive before any cover is removed from the drive to avoid an electric shock hazard. The
disconnection should be carried out with an approved isolation device before any work is performed to avoid the risk of death or serious
injury.

The motor parameter settings affect the protection for the motor, and should they be set incorrectly, this can result in damage to the motor
and encoder connected to the motor. It is essential that the correct value is entered for the
Motor Rated Current
with this affecting the
thermal protection of the motor. The default values in the drive should not be relied upon.

CAUTION
Setting the
Symmetrical Current Limit
(
B16
) to a low value or zero can result in uncontrolled movement on brake release. Ensure the
Symmetrical Current Limit
(
B16
) is set to a suitable value taking into account both the motor rated current and overload requirement in the
worst case load condition to avoid uncontrolled movement and the risk of damage to the system.
