SP600 AC Drive User Manual
2.4.4 Multiple Control Modes
The SP600 drive provides a number of user-selectable control
modes to suit different applications:
•
Sensorless Vector
•
Sensorless Vector Economizer
•
Custom Volts per Hertz
•
Fan and Pump Volts per Hertz
See the parameter description for Torque Perf Mode (53) in chapter
12 for the details of operation of each control mode.
2.4.5 Multiple Stop Methods
There are several stop methods that can be selected using drive
parameter 155:
•
Coast to Stop
•
Brake to Stop
•
Ramp to Stop
•
Ramp to Hold
Refer to the parameter descriptions in chapter 12 for more
information about these stop mode selections.
Another stop method, dynamic braking, uses an optional internal or
external DB braking resistor to dissipate stopping energy. See
parameters 161 to 163 for more information about this feature.
2.4.6 Multiple Speed Control Methods
The purpose of speed regulation is to allow the drive to adjust to
certain operating conditions, such as load change, and compensate
for these changes in an attempt to maintain motor shaft speed
within the specified regulation percentage.
The Speed Mode parameter (80) selects the speed regulation
method for the drive and can be set to one of three choices:
•
Open Loop - No speed control is offered
•
Slip Comp - Slip compensation is active
•
Process PI - The PI loop sets the actual speed based on process
variables
Refer to parameter 80 in chapter 12 for more information.
