Phenomenon
Estimated cause(s)
Exemplar measures to be taken
Slower motor revolu-
tion at low speeds than
what is expected
Insufficient output volt-
age, which in turn ren-
ders the torque
insufficient
Make an adjustment by incrementing the automatic torque
boost voltage compensation gain [HC101] by approximately
5% each time.
Insufficient frequency
correction, which in
turn renders the torque
insufficient.
Make an adjustment by incrementing the automatic torque
boost slip compensation gain [HC102] by approximately 5%
each time
A heavy load lowers
the revolution fre-
quency of the motor.
Insufficient frequency
correction, which in
turn renders the torque
insufficient.
Make an adjustment by incrementing the automatic torque
boost slip compensation gain [HC102] by approximately 5%
each time
A heavy load raises
the revolution fre-
quency of the motor.
An excessive fre-
quency correction
raises the frequency.
Make an adjustment by decrementing the automatic torque
boost slip compensation gain [HC102] by approximately 5%
each time
With a heavy load, an
acceleration causes
an over current.
An excessive voltage
correction increases
the current.
Make an adjustment by decrementing the automatic torque
boost voltage compensation gain [HC101] by approximately
5% each time.
An excessive fre-
quency correction
raises the frequency.
Make an adjustment by decrementing the automatic torque
boost slip compensation gain [HC102] by approximately 5%
each time
