WARNING! Electrical Shock Hazard. High voltage will be supplied to the motor when Stationary Auto-Tuning is performed even with the
motor stopped, which could result in death or serious injury. Do not touch the motor until Auto-Tuning has been completed.
When Auto-Tuning cannot be performed, set up the maximum frequency and voltage in the E1-
oo
parameters and enter the
motor data manually into the E2-
oo
parameters.

Acceleration/ Deceleration Times and S-Curves
There are two sets of acceleration and deceleration times which can be set in the C1-
oo
parameters. The default activated
accel/decel times are C1-01/C1-02. Adjust these times to the appropriate values required by the application. If necessary, S-
curves can be activated in the C2-
oo
parameters for softer accel/decel start and end.

Reference and Run Source
The drive has a LOCAL and a REMOTE mode.
Status
Description
LOCAL
The Run/Stop command and the frequency reference are entered at the operator keypad.
REMOTE
The Run command source entered in parameter b1-02 and the frequency reference source entered in parameter b1-01 are used.
If the drive is operated in the REMOTE mode, make sure that the correct sources for the frequency reference and run command
are set in parameters b1-01/b1-02 and that the drive is in the REMOTE mode.
The LED in the LO/RE key indicates where the Run command is input from.
