FOLLOWER
Use the Follower mode to follow an external signal at a ratio that you will most likely define. The Follower
SP (CP-220) sets the ratio at which the follower will operate with respect to the Lead. The Ratio is the
desired Feedback EU/Tm per Lead EU/Tm in velocity mode of operation.
Ratio =
Follower speed (feet/min. of the follower)
Lead speed (feet/min. of the lead)
The Ratio is set by the Follower SP (CP-220), the Ratio can be considered to be equal to the Follower SP.
ScaledRef = FI1RPM * Follower SP * EU FI2 * PPR FI2
Time Base * Pulses FI2
When the RUN Mode (CP-202) is set to “4” (Inverse Follower), the Ratio can be considered to be equal to
1/Follower SP.
The Max SP Fol (CP-221) and Min SP Fol (CP-222) determine the maximum and minimum value that can be
entered into Follower SP (CP-220). They define the range for both positive and negative values; they are
magnitude limits.
