OPEN-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. An encoder does not need to be connected for open-loop.
Open-Loop Operation Set-up
1) Enter / verify that the drive is set to run in Open-Loop in Drive Mode (U9)
Motor Parameter Set-up
2) Firstly select one of the default motors for
the MOTOR ID (A5) parameter, as a result
typical V/F patterns are loaded via the
MOTOR ID (A5) a typical example is
shown in Table 1 OL.
It is possible to optimize the V/F pattern if
required however often our default values
will suit most motors and installations.
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 motors.
NOTE
: if you are experiencing operation issues, the
stator resistance can be measured, and calculated
using the following formula.
