:
Starting Frequency
= 0.1 - 10Hz
The Inverter can start at 5Hz and still have an operational control range of 0.1 - 60Hz. To
accomplish this, (
Fn_07
) will need to be set at 0Hz and (
Fn_42
) at 5Hz.

:
Stopping Mode and Brake Resistor Protection
xxx0
: Decel to Stop
xxx1
: Coast to Stop
xx0x
: Braking Resistor Overheat Protection disable
xx1x
: Braking Resistor Overheat Protection enable
Note:
If (
Fn_44
) is set for Coast to Stop, the Inverter will cut off the output after receiving a stop
instruction and the motor will coast to a stop.
If (
Fn_44
) is set for Decel to Stop, the Inverter will decelerate to the frequency set by (
Fn_54
) after
receiving deceleration instructions. The output voltage level set at (
Fn_55
) the Inverter will stop
after the time period set by (
Fn_53
).
If (
Fn_44
) is set for protection of the Built-in Braking Transistor, and the Inverter decelerates too
frequently, the braking transistor and braking resistor may overheat causing the Inverter to trip.
(OH1 will be indicated on the Keypad display). The Inverter can be manually restarted after the
braking resistor has cooled off. If the braking resistor is damaged and leads to OV-C trip,
deceleration time must be increased or the external braking resistor replaced.
