Chapter 12 Description of Parameter SettingsCP2000
12.1-08-7
Feedback Signal Detection Time
Default: 0.0
Settings 0.0–3600.0 sec.
Pr.08-08 is valid only for ACI 4–20 mA.
This parameter sets the detection time for abnormal PID feedback. Setting the detection time to
0.0 disables the detection function.
Feedback Signal Fault Treatment
Default: 0
Settings 0: Warn and continue operation
1: Fault and ramp to stop
2: Fault and coast to stop
3: Warn and operate at last frequency
This parameter is valid only for ACI 4–20 mA.
AC motor drive acts when the analog PID feedback is abnormal.
Sleep Reference
Default: 0.00
Settings 0.00–599.00 Hz or 0–200.00%
Determines the sleep frequency, and if the sleep time and the wake-up frequency are enabled or
disabled. When Pr.08-10 = 0: disabled; when 08-10 ≠ 0: enable.
Wake-up Frequency
Default: 0.00
Settings 0.00–599.00 Hz or 0–200.00%
When Pr.08-18 = 0, the unit for Pr.08-10 and that for Pr.08-11 switch to frequency. The settings
become 0.00–599.00 Hz.
When Pr.08-18=1, the unit for Pr.08-10 and that for Pr.08-11 switch to percentage. The settings
then switch to 0–200.00%.
The percentage is based on the current command value, not the maximum value. For example, if
the maximum value is 100 kg, and the current value is 30 kg, then if Pr.08-11=40%, the value is
12 kg.
Pr. 08-10 uses the same logic for calculation.
Sleep Time
Default: 0.0
Settings 0.0–6000.0 sec.
When the frequency command is smaller than the sleep frequency and less than the sleep time,
the frequency command is equal to the sleep frequency. However, the frequency command
remains at 0.00 Hz until the frequency command becomes equal to or larger than the wake-up
frequency.
