What are the three types of “My function” available on the TOSHIBA TOSVERT VF-AS1?
The TOSHIBA TOSVERT VF-AS1 “My function” includes the following three types:
1. Logic input/output My function: This simplifies relay sequence operations.
2. Analog input My function: This changes parameter settings by the analog input signals.
3. Analog output My function: This gets the analog output signals of the maximum and minimum values displayed by the monitor function.
How is the Logic input/output My function structured on the TOSHIBA TOSVERT VF-AS1?
The logic input/output My function consists of 7 units of the same composition. Each unit consists of 4 steps, making 28 steps in total. The structure is as follows:
Step 1: Data read (LD) command.
Step 2: Command for performing the desired function and the object to which the command is issued.
Step 3: Command for performing the desired function and the object to which the command is issued.
Step 4: Data transfer (ST) command.
How do I enable or disable the “My function” on the TOSHIBA TOSVERT VF-AS1?
You can enable or disable the function using parameter F977. Note that the setting of parameter F977 cannot be changed when the inverter is in operation.
| Title | Function | Adjustment range | Default setting |
|---|---|---|---|
| F977 | My function selection | 0: Deselect 1: My function + permission signal 2: My function always ON |
0 |
0 (Unselected): Disables My function. All My function settings are ineffective.
1 (My function + enabling signal): Puts My function into a standby state. My function starts working when an ON signal is sent to the terminals to which the input terminal functions 64 and 65 (My function RUN signal) are assigned.
2 (My function always enabled): Enables My function as soon as the inverter is turned on.
How do I configure the TOSHIBA TOSVERT VF-AS1 to perform the ST+F function by sending a signal to one terminal?

How do I set the acceleration/deceleration rate using the Analog Input My Function on the TOSHIBA TOSVERT VF-AS1?
To allow the acceleration/deceleration rate to change in proportion to the analog input value (e.g., using the RR/S4 terminal), follow these steps:
Example settings:
FH = 80 (Sets the maximum frequency at 80Hz.)
F959 = 2 (Selects the RR/S4 terminal.)
F961 = 1 (Selects acceleration/deceleration rate.)
F210 = 0 (Selects 0%.)
F211 = 20.0 (Selects 20Hz.)
F212 = 100 (Selects 100%.)
AuF2 = 80.0 (Selects 80Hz.)
With these settings, if the RR/S4 input value varies from 0 to the maximum value, the acceleration/deceleration rate changes by a factor of 0.25 to 1.
