12.1-14-1
14 Protection Parameters (2)
You can set this parameter during operation.
Extension Card Input Terminal Selection (AI10)
Extension Card Input Terminal Selection (AI11)
Default: 0
Settings
0: No function
1: Frequency command
(in MH300 series, this function can be the torque limit in torque control mode)
2: Torque command (torque limit in speed mode)
3: Torque compensation command
4: PID target value
5: PID feedback signal
6: PTC thermistor input value
7: Positive torque limit
8: Negative torque limit
9: Regenerative torque limit
10: Positive / negative torque limit
11: PT100 thermistor input value
13: PID compensation value
1: This function can be the torque limit in torque control mode.
When you use analog input as PID reference target input, you must set Pr.00-20 to 2 (external
analog input).
Setting method 1: Pr.14-00–14-01 set 1 as frequency command.
Setting method 2: Pr.14-00–14-01 set 4 as PID reference target input.
If the setting value 1 and setting value 4 exist at the same time, AI10 input has highest priority to
become the PID reference target input value.
When you use analog input as the PID compensation value, you must set Pr.08-16 to 1 (Source
of PID compensation value is analog input). You can see the compensation value with Pr.08-17.
When you use the frequency command, the corresponding value for 0– ± 10 V / 4–20 mA is
0–maximum operation frequency (Pr.01-00).
When you use the torque command, the corresponding value for 0– ± 10 V / 4–20 mA is
0–maximum output torque (Pr.11-27).
When you use torque compensation, the corresponding value for 0– ± 10 V / 4–20 mA is 0–rated
torque.
When the settings for Pr.14-00 and Pr.14-01 are the same, the AI10 is selected first.
