MOTOR ID
(Motor Identification) This parameter allows
for the selection of specific sets of motor
parameters. This is yet to be determined for
DC machines.
- - - N Y
RATED MOTOR
CURR
(Rated Armature Amps) Motor armature
amps. Note: value should be obtained from
the motor nameplate.
amps 0.0 1.0 – 400.0 N Y
ARMATURE
VOLTAGE
(Rated Armature Voltage) Rated motor
armature circuit voltage. Note: value should
be obtained from the motor nameplate. volts 0 55 – 600 N N
FULL FLD
CURRENT
(Full Field Current) This parameter sets
motor field amps at low speed. Note: value
should be obtained from the motor
nameplate.
amps 0.0 1.0 – 40.0 N N
WEAK FLD
CURRENT
(Weak Field Current) This parameter sets
the motor field amps at contract. Adjust as
necessary to obtain rated armature volts at
contract speed at full load up. May be the
same as or lower than Full field Amps for
motor field weakening. Motor field current
will automatically begin to weaken when
motor speed is Contract Speed x Weak
Field/Full Field and follow a profile for
constant CEMF.
amps 0.0 1.0 – 40.0 N N
STANDBY FIELD
(Standby field Amps) Motor field current
during drive standby conditions. Motor
current will automatically drop to this level
when idle after STNDBY FIELD TIME has
expired.
amps 0.0 0.0 – 40.0 N N
FLUX CNFRM
LEVEL
(Flux Confirm Level) Determines the
minimum motor field current necessary
before drive is allowed to start. Arranged as
a percent of Full Field ampere setting. This
ensures that pre-torque current to motor will
produce adequate torque when the elevator
Brake is released. A lower setting will allow
the drive to come alive earlier in the start
cycle to help prevent unnecessary starting
delays. Units in percent of full field.
% 85.0 25.0 – 99.0 N N
ARMATURE IR
DROP
(Armature IR Drop) Adjusts motor armature
current regulator for expected current x
resistance voltage drop of motor armature
circuit at rated current. Includes motor
armature, inter-poles and wiring resistance.
Enter as a percent of rated armature volts.
This parameter also affects the sensitivity of
the fault, Encoder Fault.
Note: This equation is only valid after an
Auto Tune has been done. For information
on auto tuning the motor, see page 122.
