Forward/Reverse Run Selection (For The Panel Control Only); Maximum Frequency - Toshiba TOSVERT VF-A7 Instruction Manual

5.6 Forward/reverse run selection (for the panel control only)


Function
This parameter is used to set the direction of a motor when it is started or stopped by pressing the
Run key or Stop key on the control panel. This parameter is valid only when the operation command
mode selection parameter  is set at (control panel input enabled).

Forward/reverse selection

The direction of rotation can be checked in status monitor mode.
: Forward run, : Reverse run => Refer to 8.1
When the terminal board is used for operation, the direction of rotation is switched with the
terminal F,R. Consequently, the forward/reverse run selection parameter becomes invalid.
If F and CC, as well as R and CC are connected at the same time: Reverse run (Default setting)
Use the parameter  to change the direction of rotation in this case.
=> Refer to 6.2.2 for details.
This parameter is valid only when  is set at (Operating panel enabled.)

5.7 Maximum frequency


Function
1) This parameter is used to set the range of frequencies (the maximum frequency) that the
inverter can output.)
2) The frequency is used a the reference for setting the acceleration and deceleration times.
Output freq. [Hz]
80
60
0
When increasing the , adjust the upper limit frequency parameter  as well, if necessary.

Default setting
Set the maximum frequency
according to the rating of the
motor.
The maximum frequency cannot
be adjusted during operation. So,
put the inverter out of operation
when making this setting.
