5.5.6 Automatic torque boost
MOSCON-E7 automatically adjust the output torque by detecting the
variation in a load, to provide better speed control performance.

• Normally adjustment of S5.01 is not required.
• Raise the value in S5.01 if the output wiring between inverter and
motor is long, or when the capacity of installed motor is quite smaller
than the maximum motor capacity of the inverter.
• Decrease the value in S5.01, if the excessive mechanical vibration
occurs.

• Normally adjustment of S6.01 is not required.
• Raise the value in S6.01 if mechanical vibration occurs under a light
load condition.
• Decrease the value in S6.01 if stall occurs.
• S6.03 is used in restraining from the unique current ripple in 1 phase
only(Invalidness in 3 phase).

• If S6.02=1, the performance of braking is increased. However, since
frequent braking under this condition may damage the inverter, use this
function carefully.
