3: AI1
There are two analogue input terminals: AI1, AI2.
In this User manual, only AI1 is introduced.
According to parameter P08.03, AI1 has three functions:
P08.03=0, AI1 is speed reference
P08.03=1, AI1 is the speed limit under Torque control mode
P08.03=2, AI1is the Torque error
About AI1signal mode, there are current mode and voltage mode, for details please refer to the
explanation of parameter P00.05 (P08.02).

6: DI7 Pulse input
When P09.24=2, DI7 function is input of reference channel (by input pulse)
For example:
The maximum frequency of input pulse (P09.27) is 20.0kHz, and actual input pulse is
10.0kHz.
The percentage of DI7 pulse input (P09.38) is 50.0%. Then the reference is:
Reference =DI7 input percentage (P09.38)
×
