14 Extension Card Parameters
 Extension Card Input Terminal Selection (AI10)
 Extension Card Input Terminal Selection (AI11)
Settings
 When the setting for Pr.14-00 and Pr.14-01 are the same, the AI10 is selected first.
 Analog Input Filter Time (AI10)
Analog Input Filter Time (AI11)

Settings
 The input analog signal of terminal AI1 and AI2 often includes interferences, which will affect the
stability of the control. Use these input delays to filter a noisy analog signal.
 When the setting for the time constant is too large, the control is stable but the control response
is slow. When the setting for time constant is too small, the control response is faster but the
control may be unstable. For optimal setting, adjust the setting according to the control stability
or the control response.
 Analog Input 4–20mA Signal Loss Selection (AI10)
Analog Input 4–20mA Signal Loss Selection (AI11)

Settings
 This parameter determines the treatment when the 4–20 mA signal is lost, when Pr.14-18 = 2,
Pr.14-19 = 2.
 When the setting for Pr.14-18 or Pr.14-19 are 0 or 1, the voltage input to AVI and ACI terminal is
0: Disable
1: Frequency command
2: Torque command (torque limit in speed mode)
3: Torque compensation command
4: PID target value
5: PID feedback signal
6: Thermistor (PTC / KTY-84) 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 amount
0.00–20.00 sec.
0: Disable
1: Continue operation at the last frequency
2: Decelerate to 0Hz
3: Stop immediately and display ACE
