 When min. output frequency
≦ PID frequency ≦ lower bound of frequency and sleep function is enabled
(output frequency
≤
sleep frequency and time > detection time), frequency will be 0 (in sleep mode). If sleep
function is disabled, frequency command = lower bound frequency.
 When PID frequency < min. output frequency and sleep function is enabled (output frequency
≤
sleep
frequency and time > detection time), output frequency =0 (in sleep mode).
If output frequency
≤
sleep frequency but time < detection time, frequency command = lower frequency. If
sleep function is disabled, output frequency =0.

Feedback of PID physical quantity value Unit: 0.1
Settings 1.0 to 99.9 Factory Setting: 99.9
 When Pr.00.04 is set to 8, it will display 00:00 as follows.
 This parameter is used only for display and has no relation with Pr.00.13, Pr.00.14, Pr.02.18 and Pr.02.19.
