The specific acceleration/deceleration time shall be determined by the actual requirements on the device.
If the device needs to be stable during acceleration and deceleration:
Increase P02.13 (acceleration time 1) and P02.14 (deceleration time 1).
If the device needs to be quickly accelerated and decelerated:
Too short acceleration and deceleration time will cause overcurrent during acceleration (Er.oC1) and overvoltage
during deceleration (Er.oU2). Thus, well-matched resistors are required, and dynamic braking should be enabled
through the function code.
