12.1-14-1
14 Extension Card Parameters
 This parameter can be set during operation.

Extension Card Input Terminal Selection (AI10)

Extension Card Input Terminal Selection (AI11)
Default: 0
Settings 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
 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)
Default: 0.01
Settings 0.00–20.00 sec.
 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 sign
al.

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 unst
able. For optimal setting, adjust the setting according to the control st
ability
or the contr
ol response.

Analog Input 4–20mA Signal Loss Selection (AI10)

Analog Input 4–20mA Signal Loss Selection (AI11)
Default: 0
Settings 0: Disable
1: Continue operation at the last frequency
2: Decelerate to 0Hz
3: Stop immediately and display ACE
 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 i
