6-11 Forward and Reverse Drive Prohibition Functions
Precautions for Correct Use
A load on the vertical axis and so forth may fall due to its own weight in the drive prohibition input
state. To prevent the load from falling, set immediate stop torque for deceleration and servo lock
for stop (set value: 2) in Stop Selection for Drive Prohibition Input (Pn505), or limit the operation
using the Host Controller rather than using this function.
Because an immediate stop will force the motor to decelerate quickly, the position error will
momentarily be a large value during position control, and Err24.0 "error counter overflow" or
Err34.0 "overrun limit error" may occur.In such a case, set the Position Counter Overflow Level
(Pn014) and the Overrun Limit Setting (Pn514) to appropriate values.
