Chapter 4: Servo Control Operation 4.1 Current Command Input The Dragonfly and Bu tterfly have a sin gle differen tial input. The input ope rating voltage range is ± 3.75 V, meaning that a 3.75 V signal will result in a f ully rated peak current. The current limit circuits will override this signal if the peak duration exceeds 2.
4.2.2 Exte rnal Resistor Connect an external resistor between terminal J 1 /9 (ECLC) and terminal J 1 /8 (ECLRET). The resistor va lue is given by: 0 < RECLC < 36.4 K ( 1 /8 Watt) At RECLC greater than 36.4 K, the current limit will be internally clamped to the nominal value.
4.2.5 Exte rnal Resistor Connect an external resistor between terminal J 1 / 1 4 (ECLP) and terminal J 1 /8 (ECLRET). The resistor va lue is given by: 0 < R ECLP < 36.4 K (1/8 Watt) At RECLP greater than 36.4K, the current limit will be internally clamped to the nominal value.
