AC70 VC CONTROL FREQUENCY INVERTER MANUAL
FUNCTION PARAMETER DETAILED SPECIFICATION
84
1: Opposite to the default direction
Actual rotation direction is opposite to the requirement. The actual
direction will be change.
2: Reverse running forbidden
When this parameter is set as prohibition, all the reverse command from
Running control command selection (operator keypad, external terminal, RS485 communication, bipolar VS2 and
program running) are invalid.
The setting will not be modified after the factory default setting.
Note: 1. When the reverse running forbidden is selected, when the bipolar control receiving the reverse
frequency command, the inverter will be operation with 0 speed, the case is the same, inverter will be
operate with 0 speed during program running control if there are some certain step speed reverse direction
are set.
2. All reverse command will be auto turn to running command, running with forward direction.
E-47
FOR/REV dead zone time
Range:0.0-10.0s Default:0.0s
The function defined the transient waiting time from forward to reverse or from reverse to forward during 0Hz.
FOR/REV dead zone time special designed for big inertia load application which has mechanical dead zone
required.
E-48
Cooling fans running selection Range:0,1,2
Default:
※
Uses select cooling fan running mode.
0: Fan runs when inverter switch on. Cooling fan stop when under voltage condition, it runs when power supply is
stable.
1: Relates with temperature during inverter stop mode, fan runs when inverter running
Fan stop or not is relate to temperature of module during stop mode, fan would operate when the temperature is
above 45
℃
, stop when module temperature lower 40
℃
. Fan runs immediately when inverter receives a run
command.
2. Fan stop during inverter stop mode, relates with temperature during inverter running. Fan stop or not is related to
temperature of module during inverter running mode, fan runs when the temperature of module is above 45
℃
,
stops when temperature of module is lower than 40
℃
. Fan stops always during inverter stop mode.
Note: Use this function correctly enable extend fans working life.
