It is to set the transient time during w hich the output frequency is 0 in the FWD/REV transient process
of inverter.
It is shown as following figure:
Fig. 6-3 DCBra ke Diagram
Fig. 6-4 FWD/REV Dead Time Diagram
If operating command channel is set to terminal control, s ystem will detect terminal status
automatically during inverter power on.
0: Terminal command invalid when power on. Inverter will not run if it detect operating command termi nal
is valid. When the operating command terminal is inv alid and enable this terminal again, invert er will run.
1: Terminal command valid when power on. Inverter will startup automatically after initiali zation is
finished if it detect operation command terminal is valid.
Note: Customer should be careful when you select this function, it may cause severe consequence.
0: suitable for constant torque load of d esignated nominal parameter.
1: suitable for variable torque l oad (such as fan and pump).
Constant torque(B model) inverter can dri ve larger variable torque(P model) load directly.
For example,
DZB300B0220L4
inverter is set 22KW B model as default, if you want to drive 30KW
fan, you should
Set F1.00 as 1
Set F1 group motor parameter again

Note: please set these codes according to motor na meplate parameters. The superior performances
of vector control require precise motor parameters.
Note: resetting of motor rated power (F1.01) can initialize motor parameter F1.02-F1.10.
DZB series inverter provides parameter self-learning function. Accurate parameter self-learning comes
from correct setting of motor nameplate parameters.
In order to ensure the control perform ances, please do the motor setting based on t he inverter standard
adaptive motor. If the motor rated power has a too big difference to the standard adaptive motor, the inverter
control performances will be deteriorated distinctly.
