Operation with CC-Link

By providing the inverter (A500) with CC-Link, are the following operations possible?
1. Can I change the speed while the inverter is operating? (Just as done using analog signals.)
2. Can I change the acceleration/deceleration time when the inverter starts and stops? I am considering increasing and decreasing the load to do this.
3. If the above two operations are possible, are they possible while the inverter running?
4. When switching between multiple motors, is there a method to utilize the tuning data? Or is it required to set the parameters each time each motor starts?

Answer

1. By changing RWw1 while RYD is ON, you can change the inverter's frequency.
You cannot do this with RYE.
You need to turn OFF and then ON RYE each time you change RWw1.

2. This function can be set with the Pr77. Note that initial setting can only be changed while the inverter is not operating.

3. No problem with frequency setting.
To allow for changing parameters during operation, set Pr.77 = 2.

4. You need to tune each motor offline, take a note of the motor constant values, and then set them each time you switch between motors.
