1-25 Motor Nominal Speed
Range: Function:
Application
dependent* [100 - 60000 RPM] Enter the nominal motor speed value from the motor nameplate data. This data is used for calcu-
lating automatic motor compensations.
NOTE!
This parameter cannot be adjusted while the motor is running.
1-28 Motor Rotation Check
Option: Function:
Following installation and connection of the motor, this function allows the correct motor rotation
direction to be verified. Enabling this function overrides any bus commands or digital inputs, except
External Interlock and Safe Stop (if included).
[0] * OFF Motor Rotation Check is not active.
[1] Enabled Motor Rotation Check is enabled. Once enabled, display shows:
"Please Note! Motor may run in wrong direction".
Pressing [OK], [Back] or [Cancel] will dismiss the message and display a new message: “Press [Hand on] to start the motor. Press [Cancel] to abort”.
Pressing [Hand on] starts the motor at 5 Hz in forward direction and the display shows: “Motor is running. Check if motor rotation direction is correct.
Press [Off] to stop the motor”. Pressing [Off] stops the motor and resets par. 1-28
Motor Rotation Check
. If motor rotation direction is incorrect, two
motor phase cables should be interchanged. IMPORTANT:
Line power must be removed before disconnecting motor phase cables.
3-41 Ramp 1 Ramp-up Time
Range: Function:
Application
dependent* [Application dependant] Enter the ramp-up time, i.e., the acceleration time from 0 RPM to par. 1-25
