Time
of the anti-breakdown operation during the constant power operation
can be selected.
Right acceleration and deceleration time can be selected according
to the inertia of load to ensure stable operation.
Setting of anti-breakdown function code Cd045 is described
below:
Cd045=0:No protective function
=1:Use protective function V/F mode only(Currently selected
acceleration/deceleration time)
=2:Use protective function V/F mode
only(Acceleration/Deceleration time = Cd019,Cd023: 1st
acceleration/decelerationtime)
=3:Use protective function V/F mode
only(Acceleration/Deceleration time = Cd020,Cd024: 2nd
acceleration/decelerationtime)
=4:Use protective function V/F mode
only(Acceleration/Deceleration time = Cd021,Cd025: 3rd
acceleration/decelerationtime)
=5:Use protective function V/F mode
only(Acceleration/Deceleration time = Cd022,Cd026: 4th
acceleration/decelerationtime)
=6:Use protective function V/F mode andsensorless vector control
mode (Acceleration/Deceleration time = Cd019
=7:Use protective function V/F mode andsensorless vector control
mode (Acceleration/Deceleration time = Cd020,Cd024: 2nd
acceleration/decelerationtime)
=8:Use protective function V/F mode andsensorless vector control
mode (Acceleration/Deceleration time = Cd021,Cd025: 3rd
acceleration/decelerationtime)
=9:Use protective function V/F mode andsensorless vector control
mode (Acceleration/Deceleration time = Cd022,Cd026: 4th acceleration/decelerationtime)
