6.5 Remote Operation
The drive unit is now ready for terminal strip control.
1. Set the speed reference command to zero.
2. Start the drive.
3. Slowly increase the speed potentiometer to full speed.
4. Stop the unit and proceed to Section 6.6 for parameter programming
for the specific application. For further detailed descriptions of parameter
programming see Chapter 5.
6.6 Initial Programming
This section details recommended programming. The
CSD Series
is provided with factory preset parameters that are suitable for most
applications. Review the factory settings for each parameter before
making any changes. Factory settings are noted in each of the
following sections.
6.6.1 Motor Overload
Factory Setting:
Fn70 = Depends
on model (Refer to chart at right)
Fn69 = 0 (Standard Motor)
This function allows you to enter the motor current into the CSD for
proper thermal motor protection. Check your motor name plate for
exact FLA. For your convenience, approximate standard motor FLAs
are listed in the chart to the right.
1. Program Fn70 with the motor rated current.
2. Program Fn69 to:
Standard motor = 0000
Drive duty motor = 0010
Note: Motortronics recommends that, whenever possible, the
application use an “drive duty” motor to prevent premature failures
specific to variable speed applications. See Chapter 1 - Introduction,
Section 1.4.4 for more information.
6.6.2 Setting V/f Pattern
Factory Setting: Fn05 = 9
If it is not a general purpose, 60 Hz application, program Fn05 as
indicated in the chart to the right.
There are four basic types of loads:
•
General Purpose - loads not covered by the categories listed below.
Most applications work well with this V/f pattern.
•
Variable Torque - centrifugal fans, pumps and blowers
•
Constant Torque - conveyors
•
Constant HP - cutting or machine tools
6.6.3 Momentary Power Loss Ride-thru
Factory Setting:
Fn31 = 0.5 seconds (Range: 0-2 seconds)
Fn32 = 0 (Disabled)
If momentary power loss is common and the application requires
continual running through these lapses:
1. Program Fn31 = 2 (seconds)
2. Program Fn32 = 1 (enables ride-thru)
If the drive continues to trip, enable the auto restart function. See
