6. OPERATION INSTRUCTIONS
DANGER!
During operation, do not touch the non-insulated energized parts and never touch or stay too close to rotating
parts.
The rated performance values and the operating conditions are specified on the motor nameplate. The voltage and
frequency variations of the power supply should never exceed the limits established in the applicable standards.
Occasional different behavior during the normal operation (actuation of thermal protections, noise level, vibration level,
temperature and current increase) must always be assessed by qualified personnel. In case of doubt, turn off the motor
immediately and contact the nearest WEG service center.
6.1. SELECTING THE ROTATION DIRECTION
Remove the lid from the back side of the drive cover;
Use the DIP switch identified as CW / CCW to select the rotation direction between counter-clockwise (CCW) or
clockwise (CW), looking from the motor drive end (shaft);
Reinstall the lid to the back side of the drive cover after the adjust;
NOTE!
If the rotation direction is changed while the product is running, the motor will decelerate, reverse the direction
and accelerate to the same speed that was running before.
6.2.
ATTENTION!
After remove and reinstall, make sure that the lid from the back side of the drive cover is securely closed to
guarantee the protection degree.
HOW TO ADJUST SPEED
The product speed can be changed by local adjust (buttons) or remote adjust (control inputs);
To select between local or remote speed adjust:
Remove the lid from the back side of the drive cover;
Use the DIP switch identified as L / R to select between local (L) or remote (R);
Reinstall the lid to the back side of the drive cover after the adjust.
ATTENTION!
After remove and reinstall, make sure that the lid from the back side of the drive cover is securely closed to
guarantee the protection degree.
Local speed adjusts:
Remove the lid from the back side of the drive cover;
Use the two tact buttons located in the opening on the back cover to change speed;
Keep pressing the button to decelerate or accelerate the motor according identified on the nameplate;
The motor will turn off when the speed reaches a value lower than the minimum speed of the range;
The product will not go to speeds higher than the value adjusted to be the maximum speed (see 6.4
Reinstall the lid to the back side of the drive cover after the adjust.
NOTE!
g
The standard maximum speed value is preset at WEG to be the highest value of the speed range but, can be
changed by the user (see item 6.4).
The product has speed memory when operating in local speed adjustment. The last speed adjusted will be kept in
memory when the input power supply is removed. The motor will accelerate to the memorized speed when the input
power supply is reconnected.
The local controls inside the opening on the back cover of the product are totally insulated. There is no risk of shock
when touch any internal part of this opening, even when the solution is running.
ATTENTION!
After remove and reinstall, make sure that the lid from the back side of the drive cover is securely closed to
guarantee the protection degree.
