User Manual EM303B General Purpose Inverter Output Frequency(Hz) Output Frequency(Hz) Fmax Fmax Time(S) Time(S) t1 （ b ） Deceleration Time 1 t2 Figure 7-4 Acceleration/Deceleration Time （ a ） Acceleration Time 1 In Jog running mode, inverter runs at the frequency set by F0-11, the acceleration/deceleration time taken for running to Fmax is set by F0-12/F0-13. ★ Jog acceleration time is the time taken for the output frequency to rise from 0Hz up to maximum frequency Fmax. Deceleration time is the time taken for the output frequency to drop from Fmax down to 0Hz. ★ In jog running mode, keep pressing JOG ＋／－ or terminal JOG is on. Otherwise, it will be considered as the jog command cancelled.
Please note that the unit of acceleration /deceleration time is second or minute defined by F3-21. Increasing carrier frequency could reduce motor noise, but it will result in inverter heating up. When carrier frequency is higher than the default, the rated power of inverter should decrease 5% as each increment of 1 kHz carrier frequency. Correlation between motor rated power and carrier frequency is suggested as following: The setting range of carrier frequency is limited by power rating: 87 No. Function Range Unit Default Type F0-11 Jog Numeric Frequency 0.00～Fmax Hz 5.00 ● F0-12 Jog Acceleration Time 0.00～600.00 S/min 15.00 ● F0-13 Jog Deceleration Time 0.00～600.00 S/min 15.00 ● No.
