YASKAWA TOEPYAIHV6002A HV600 Drive Programming 225
Note:
If you decelerate the drive too quickly, the drive will detect an ov [Overvoltage] fault and shut off the output, and the motor will coast to
stop. To prevent motor coasting and stop the motor quickly and safely, make sure to set a Fast Stop time in C1-09 .
◆
C2: S-Curve Characteristics
Use S-curve characteristics to smooth acceleration and deceleration and to minimize abrupt shock to the load.
Set S-curve characteristic time during acceleration/deceleration at start and acceleration/deceleration at stop.
The following figure explains how S-curves are applied.
Figure 2.32 S-Curve Timing Diagram - Forward/Reverse Operation
Note:
•
If STPo [Motor Step-Out Detected] occurs when starting a PM motor, try increasing the value set to C2-01 .
• Setting the S-curve will increase the acceleration and deceleration times.
