6. OPERATING THE INVERTER
• Test Run
The inverter operates by setting the frequency (speed).
There are three types of operation modes for the VS mini J7:
1. Run command from the digital operator (local potentiometer/digital setting).
2. Run command from the control circuit terminal.
3. Run command from communications (MEMOBUS).
(Communication option card is required)
Prior to shipping, the drive is set up to receive run command and frequency reference
from the control circuit terminal. Following are instructions for running the VS mini J7
using the digital operator (with volume). For instructions on operation, refer to page
47.
Operation reference or frequency reference parameters can be selected separately as
shown below.
Name Parameter
Operation Reference
Selection
n02 = 0 --- Enables operator RUN, STOP/RESET
= 1 --- Enables control circuit terminal run/stop
= 2 --- Enables communications (MEMOBUS)
Frequency Reference
Selection
n03 = 0 --- Enables operator volume
= 1 --- Enables frequency reference 1 (parameter 24)
= 2 --- Enables voltage reference (0 to 10V) of control circuit terminal
= 3 --- Enables current reference (4 to 20mA) of control circuit terminal
= 4 --- Enables current reference (0 to 20mA) of control circuit terminal
= 6 --- Enables communications (MEMOBUS)
