12.1-14-1
14 Extension Card Parameter
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
4: PID target value
5: PID feedback signal
6: Thermistor (PTC) input value
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 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 4–20 mA Signal Loss Selection (AI10)
Analog Input 4–20 mA Signal Loss Selection (AI11)
Default: 0
Settings 0: Disable
1: Continue operation at the last frequency
2: Decelerate to 0 Hz
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 is
0–10 V or 4–20 mA. At this moment, Pr.14-10 and Pr.14-11 are invalid.
Setting 1 or 2: Displays the warning code “ANL” on the keypad. It continues blinking until the
lost ACI signal is recovered.
When the motor drive stops, the warning condition does not continue to exist, so the warning
disappears.
