Basic Terminal Run Methods - Toshiba TOSVERT VF-AS3 Instruction Manual

4. 4

Basic terminal run methods

• Do not touch terminals when the inverter's power is on even if the motor is stopped.
Touching the terminals while voltage is applied will result in electric shock.
• Do not touch switches when the hands are wet and do not try to clean the inverter with a damp
cloth.
Prohibited
This will result in electric shock.
• Turn the power on only after mounting the front cover.
When you use the inverter housed in the cabinet with the front cover removed, always close the
cabinet doors first and then turn the power on. If you turn the power on with the front cover or
Mandatory
the cabinet doors open, this will result in electric shock.

This section introduces terminal run methods with basic examples.
Input a run command and a frequency command from a digital signal (switch/relay, etc.) or analog signal
(voltage/current) from the external.
4. 4. 1 [Operation example 1] Run/stop with external signal
(frequency command with operation panel)
Input a run command externally and a frequency command from the operation panel.
• First, check connection from external contacts such as switch/relays to the control terminal.
Here is a case where the operation is controlled by a switch.
• Next, make setting so that a run command can be input externally (terminal) and a frequency
command from the operation panel.
• Then, set a frequency command on the operation panel. The motor will run with this frequency.
• After setting the above, operate the motor by using an external switch.
• The parameters to be set are <CMOd: Run command select> and <FMOd: Frequency command
select 1>.
• Control connection is explained in the case of sink logic.
• How to switch the display mode of the operation panel -> Refer to [3. 1. 2]
• Procedure to change parameter setting -> Refer to [4. 2. 3]
• Details of <CMOd: Run command select>, and <FMOd: Frequency command select 1> ->
Reference
Refer to [5. 2. 1]
• Difference of connection between sink logic and source logic -> Refer to [2. 3. 5]
• Details of operation by external signals -> Refer to [Chapter 7]
