optional communication cards and you can select one based on actual requirements. If the communication
protocol is Modbus, PROFIBUS-DP or CANopen, the corresponding serial communication protocol needs to
be selected based on the setting of P0-28.

When used as an independent frequency input channel (frequency source switched over from X to Y), the
auxiliary frequency source Y is used in the same way as the main frequency source X (refer to P0-03).
When the auxiliary frequency source is used for operation (frequency source is "X and Y operation"), pay
attention to the following aspects:
1. If the auxiliary frequency source Y is digital setting, the preset frequency (P0-08) does not take effect. You
can directly adjust the set main frequency by pressing keys ▲ and ▼ on the operation panel (or using the
UP/DOWN function of input terminals).
2. If the auxiliary frequency source is analog input (VS, AS and VS2) or pulse setting, 100% of the input
corresponds to the range of the auxiliary frequency Y (set in P0-05 and P0-06).
3. If the auxiliary frequency source is pulse setting, it is similar to analog input.
Note: The main frequency source X and auxiliary frequency source Y must not use the same channel. That is,
P0-03 and P0-04 cannot be set to the same value.
