• When the Motor Speed Goes below the Level Set in Pn507 for a Rotary Servomotor or in
Pn583 for a Linear Servomotor after the Power Supply to the Motor Is Stopped
• When the Time Set In Pn508 Elapses after the Power Supply to the Motor Is Stopped
The Servomotor will be limited to its maximum speed even if the brake reference output speed
level (Rotary Servomotor: Pn507, Linear Servomotor: Pn583) is higher than the maximum speed.
