MEMO
For the analog command, the motor speed varies at the change ratio (slope) of the
input signal, but it cannot vary faster than the preset acceleration or deceleration
time. To control the speed in response to the input signal's change ratio, set the
acceleration/deceleration time to "0".
You may turn the start signal on/off to start operation after entering the speed
setting signal. In this case, the motor speed rises or falls in accordance with the
preset acceleration/deceleration time.
Use Pr. 902 to 905 [Section 8.3.1] to change the relationship between the analog
speed command and motor speed.
