Parameter Descriptions 2-61
7000-TD002A-EN-P – September 2007
Total Acceleration Time [Total Accel Time]
Linear Number: 61
Default Value: 32.0 sec
Minimum Value: 0.0 sec
Maximum Value: 1200.0 sec
Access Level: Monitor
Read/Write: Read/Write
This parameter specifies the time the drive will take to accelerate to rated speed. It is used in conjunction
with the parameter Load Inertia to automatically calculate the acceleration and deceleration times. Any
changes to the individual acceleration ramp times will automatically change this value to reflect the new
sum, and changes to this parameter will in turn be reflected in automatic changes to the acceleration
ramp times. This parameter is not active if S-Curve percentage is any value other than 0%.
Total Deceleration Time [Total Decel Time]
Linear Number: 62
Default Value: 32.0 sec
Minimum Value: 0.0 sec
Maximum Value: 1200.0 sec
Access Level: Monitor
Read/Write: Read/Write
This parameter specifies the time the drive will take to decelerate from rated speed to standstill. It is used
in conjunction with parameter Load Inertia to automatically calculate the acceleration and deceleration
times. Any changes to the individual deceleration ramp times will automatically change this value to
reflect the new sum, and changes to this parameter will in turn be reflected in automatic changes to the
deceleration ramp times. If the drive reaches the coast speed parameter value during a stop command
deceleration, the drive will stop gating and coast to a stop. This parameter is not active if S-Curve
percentage is any value other than 0%.
Load Inertia Type [Inertia Type]
Linear Number: 63
Default Value: Low
Access Level: Basic
Read/Write: Read/Write
This parameter specifies the type of load inertia. It is used in conjunction with parameters Total Decel
Time and Total Accel Time to calculate the acceleration and deceleration times. Some examples of low
inertia applications include pumps and refiners. Some examples of high inertia loads include fans and
banbury mixers. By setting this parameter from low to high, you will increase the default acceleration and
deceleration times by a factor of 5.
The available options are:
Low The application is a low inertia load
High The application is a high inertia load
