Chapter 14 Common Functions
(2) The operation of the following function of virtual servo amplifier differs from
the actual servo amplifier.
Function Operation
External signal selection function
When "1: External input signal of servo amplifier" is set in "[Pr.80] External input signal
selection", the external signal status immediately after power supply ON is shown
below.
• Upper/lower limit signal (FLS, RLS): ON
• Proximity dog signal (DOG): OFF
Change the signal status in "[Md.30] External input signal".
(Refer to "Restrictions (3)" for details.)
When "2: Buffer memory of QD77GF" is set in "[Pr.80] External input signal selection",
the upper/lower limit signal (FLS, RLS) and the proximity dog signal (DOG) follow the
buffer memory status of the Simple Motion module even in the virtual servo amplifier.
Torque limit function
Turns ON/OFF the torque limit ("[Md.108] Servo status" high-order buffer memory
address: b13) depending on "[Md.104] Motor current value". (Refer to "Restrictions
(3)" for details.)
(3) The following monitor data of virtual servo amplifier differ from the actual
servo amplifiers. The writing operation is possible in the virtual servo
amplifier.

"[Pr.80] External input signal selection", the external input
signal status can be operated by turning ON/OFF the
following signals.
