A.5.2 Steady-State and Dynamic Performance
A WebPak 3000 drive section, when applied within the machine parameter limits and
set up with the necessary regulator parameters as listed in the Application Workbook,
will operate with the following steady-state performance specifications:
• Speed regulator with digital encoder feedback
• 0.01% of top speed over 20:1 speed range
• Speed regulator with analog tach feedback
• 1.0% of top speed over 20:1 speed range
• Current regulator
• 0.5% of rated current over 20:1 current range
• Position regulator
• 0.1% of position range
• Tension regulator
• 0.1% of maximum tension over 20:1 tension range
These steady-state performance values assume machine conditions that do not
exhibit cyclic drive speed or load profiles.
Drive response to step or ramp inputs would characterize the dynamic performance
specifications. Nominal results based on defined machine parameter limits can be
expected. However, predicting the actual values is difficult because variable machine
conditions will impact results.
The WebPak 3000 drive is capable of maintaining process continuity during machine
transient conditions as long as the machine parameters fall within their defined
boundaries. Any operating requirements that fall outside of the parameter limit will
require specific system analysis. Contact Reliance Electric for assistance.
