Load And Motor Parameters 100 Through 118 - Trane TR1 6002 Installation And Operation Manual

Load and Motor
Parameters 100 through 118
This parameter group controls output power and other output
characteristics of the drive.
For correct operation, motor nameplate data must be entered into
parameters 102 through 106 either through the Quick Menu or the
Extended Menu. In addition, automatic motor adaptation, DC braking
and motor thermal protection can be set by this parameter group.
100 Configuration
Value:
★ Open loop (OPEN LOOP)
Closed loop (CLOSED LOOP)
Function:
This parameter is used for selecting closed loop or open loop
operation.
Description of choice:
If Open loop is selected, speed control is changed directly by the
speed reference signal. Any feedback signal applied to the drive will
have no effect on the drive’s speed.
If Closed loop is selected, the internal process regulator is available to
accept feedback signal(s) to provide the desired speed regulation.
It is important to set parameter 100,
Configuration, properly when closed loop
operation is required. When open loop is
selected, parameters associated with setting up
PID controller are not accessible.

101 Torque Characteristics
Value:
★ Automatic Energy Optimization
(AEO FUNCTION)
Parallel motors (MULTIPLE MOTORS)
Function:
This parameter configures the drive for single or multiple motor
operation.
The AEO function will automatically and continuously monitor the load
and adjust the output voltage to maximize motor and drive efficiency
and performance. After the motor reaches the set speed, the AEO
function reduces the output voltage to the motor, if the load will allow.
When the load is light, the voltage is reduced, as shown in the graph
below. This lower voltage reduces motor heating and motor noise, and
increases efficiency.
Description of choice:
Select Automatic Energy Optimization (AEO) for all single motor
applications. When AEO has been selected, only one motor may be
connected to the drive at a time.
Select Parallel motors when more than one motor is connected in
parallel to the output. In this case, it is necessary to set a start voltage in
parameter 108, Start Voltage of Parallel Motors.
To optimize AEO for use with motors having
more than 4 poles, see parameter 118, Motor
Power Factor.
