CLOSED-LOOP QUICK START-UP GUIDE
NOTE:
This quick start-up guide just outlines the general parameters that should be changed / verified
when a drive is installed with information that are readily available. The drive will
not
run if
only
these
parameters are set. Because different controller manufacturers have different interfaces, it is
recommended that the parameters in the drive be set to what is recommended by the elevator
controller in their technical manual.
Closed-Loop Operation Set-up
1) Enter / verify that the drive is set to run in Closed-Loop in Drive Mode (U9)
Motor Parameter Set-up
2) Select one of the two default motors (either 4 or 6 pole) for the MOTOR ID (A5) parameter (or
select a valid motor ID, if available).
Enter / verify the following from the motor’s
nameplate:
Motor HP or KW rating (RATED MTR
POWER(A5))
Motor Voltage (RATED MTR VOLTS(A5))
Motor Excitation Frequency in Hz (RATED
EXCIT FREQ(A5))
Rated Motor current (RATED MOTOR
CURR(A5))
Number of Motor Poles (MOTOR POLES(A5))
Rated Motor Speed at full load in RPM (RATED MTR SPEED(A5))
Note
: The rated motor rpm must be full load speed.
If synchronous speed is given, the motor rated rpm
can be estimated by:
97.5% of synchronous speed for Nema type B
motor design
94% of synchronous speed for Nema type D
motor design
3) Use the default value for Stator Resistance
(STATOR RESIST(A5)) of 3.5% for 4 pole
machines and 1.5% for all other poles.
NOTE
: if you are experiencing operation issues, the
stator resistance can be measured, and calculated
using the following formula.
Encoder Set-up
4) Verify the encoder has been selected and installed in accordance with the following:
Electrical interference and mechanical speed modulations are common problems that can result in
improper speed feedback getting to the drive. To help avoid these common problems, the
following electrical and mechanical considerations are suggested.
IMPORTANT-
Proper encoder speed feedback is essential for a drive to provide proper motor
control.
