*1 Acceleration time and deceleration time may be limited. For details, refer to the following.
Page 310 Limit of acceleration time/deceleration time
*2 This is the calculation formula when unit of V is [/s]. When other than [U/s], calculate by converting into [U/s].
*3 Target acceleration/target deceleration may be adjusted by acceleration/deceleration waveform adjustment. For details, refer to the
following.
