2.6 Restrictions for Feedback Pulse Inputs
2.6.1 Restrictions for SERVOPACK Pulse Output Frequency
The upper limit to the SERVOPACK pulse output frequency is shown below.
Œ However; Motor Speed at a Divided Output Pulse Frequency of 1.6 MHz = 1.6 × 10 6 × 60 ÷ Pn212 set value
The following tables show the relationship between the number of encoder bits and the maximum speed for a pulse fre-
quency of 1.6 MHz output by
Σ-II/Σ-III/Σ-V SERVOPACK.
Application must be within the ranges shown in these tables when a Σ-II/Σ-III/Σ-V SERVOPACK is connected to the
SVA-01 Module.
