(3) Setting and Verification before Operation
When setting up the VS-686SS5, make sure to follow the procedures below. Mistakes in set-
up order may cause values to be written over resulting in poor operation.
STEP 1 Control method setting (Page 43)
STEP 2 Constant torque/variable torque motor settings (Pages 44 to 47)
STEP 3 Motor capacity selection (Pages 44 to 47)
STEP 4 Nameplate value setting (Pages 44 to 47)
The VS-686SS5 is equipped with two current vector control methods (with or without PG).
Either method can be easily selected by using the digital operator to meet user application
needs. Open loop vector control is set at the factory prior to shipment. In the following cases,
follow the procedures below to set and verify the control method and motor related constants.
