Setting details
Set the arrangement for the
speed change gear 1.
Set the smoothing time constant
for the speed change gear 1.
Set the numerator for the speed
change ratio 1.
Set the denominator for the
speed change ratio 1.
Set the arrangement for the
speed change gear 2.
Set the smoothing time constant
for the speed change gear 2.
Set the numerator for the speed
change ratio 2.
Set the denominator for the
speed change ratio 2.
(1) [Pr.434] Speed change gear 1 (D15046+150n),
[Pr.490] Speed change gear 2 (D15052+150n)
Set the arrangement for the speed change gear 1 or speed change gear 2.
The speed change gear 1 and speed change gear 2 cannot be set in the same
arrangement.
If they are set in the same arrangement, the major error (error code: 1748)
occurs and the synchronous control cannot be started.
• 0: No speed change gear ........................ Speed change is not processed, and
