CONTRACT
CAR SPD
(Contract Car Speed)
Adjusts the
elevator contract speed in feet per minute
(fpm) or meters per second (m/s).
fpm 100.0 0.0 – 1500.0
N Y
m/s 2.000 0.000 – 8.000
CONTRACT
MTR SPD
(Contract Motor Speed)
Sets motor rpm
when commanded to run at elevator
contract speed. The speed regulator
actually regulates RPM x Encoder PPR
pulses per second. Trim this value to fine
tune actual elevator speed.
rpm 50.0 30.0 – 3000.0
N Y
RESPONSE
(Response)
Sets the sensitivity of the
drive’s speed regulator in terms of the
speed regulator bandwidth in radians.
The responsiveness of the drive as it
follows the speed reference will increase
as this number increases. If the number
is too large, the motor current and speed
will be jittery. If this number is too small,
the motor will be sluggish.
rad/sec 5.0 1.0 – 20.0
N N
INERTIA
(Per Unit System Inertia) This parameter
is the inertia/torque ratio as seen by the
drive. It affects internal gain of the speed
regulator. This time in seconds is the
time it would take the motor to accelerate
a load-balanced elevator to contract
speed at rated torque.
sec 2.00 0.25 – 10.00
N N
INNER LOOP
XOVER
(Inner Loop Crossover) This parameter
is used as a stiffness factor. Higher
settings make the drive more responsive
to load changes and can help minimize
rollback. Because of the amount of
responsiveness due to a high setting, the
drive is more sensitive to speed
disturbances and this parameter can
affect ride quality. Note: this parameter is
only used when SPEED REG TYPE (C1)
= ELEV SPD REG. See SPD PHASE
MARGIN (A1) if using PI REG.
rad/sec 2.0 0.1 – 20.0
N N
CURRENT LIMIT
(Armature Current Limit) This parameter
sets armature current limit for DC motor
applications.
% 250.0 0.0 – 300.0
N N
GAIN REDUCE
MULT
(Gain Reduce Multiplier)
This parameter
is the percent of ‘response’ the speed
regulator should use in the ‘low gain’
mode. This value reduces the
RESPONSE value when the drive is in
‘low gain’ mode. (i.e. setting this
parameter to 100% equals no reduction
in gain in the ‘low gain’ mode)
% 100 10 – 100
Y N
GAIN CHNG
LEVEL
(Gain Change Level) When the HI/LO
GAIN SRC in submenu C1 is set to
internal, the drive will control the high/low
gain switch. This parameter sets the
speed reference level, above which, the
drive is in ‘low gain’ mode. Units in
percent of rated speed.
For more information, see GAIN CHNG
LEVEL on page 48.
% 100.0 0.0 – 100.0
