CP-16 ACCELERATION TIME
Acceleration Time (CP-16) controls the rate of speed change in response to setpoint changes.
This Control Parameter applies to both the Master and Follower modes of operation. Enter the
desired number of seconds to increase the motor speed from 0 to 2000 RPMs.
CP-17 DECELERATION TIME
Deceleration Time (CP-17) controls the rate of speed change in response to setpoint changes.
This Control Parameter applies to both the Master and Follower modes of operation. Enter the
desired number of seconds to decrease the setpoint in the range of 2000 to 0 RPMs.
CP-18 LAG PULSE LIMIT
The Lag Pulse Limit sets a maximum pulse error for the lagging (follower is behind in position)
feedback pulses that are maintained in the zero error loop. It may not always be desirable to
recover all of the position error lag.
CP-19 LEAD PULSE LIMIT
The Lead Pulse Limit sets a maximum pulse error for the leading (follower is ahead in position)
feedback pulses that are maintained in the zero error loop. It may not always be desirable to
recover all of the position error lead.
CP-20 MASTER ENGINEERING UNITS
The actual value of the Master Engineering Units (CP-20) if the system were to operate at the
desired maximum RPMs (refer to CP-34). This is not to be confused with the setpoint, which is
the Master Engineering Units at which you want the system to operate.
CP-21 FOLLOWER ENGINEERING UNITS
In Follower Engineering Units (CP-21), enter a number that will represent the setpoint
Engineering Units when the Lead and Follower are operating at the maximum desired RPM.
This number is usually the ratio of Max RPM Feedback (CP-34) to Max RPM Lead (CP-33).
When this number is also entered as a setpoint (CP-03 or CP-04), the Follower will operate at
Max RPM Feedback (CP-34) when the Lead is at Max RPM Lead (CP-33).
