2.2
Performance Specifications of the RD77GF
This section lists the performance specifications of the RD77GF.
*1 The speed-position switching control (ABS mode) can be used only when the control unit is "degree".
*2 When "Speed control 10
multiplier setting for degree axis function" is valid, the setting range is 0.01 to 20000000.00 (degree/min).
