3. OPERATING INFORMATION

WARNING

The equipment must not be switched on until after its cover has been fitted and ther cove screws have been tightened to the correct torque.

After the power has been turned off, you must always wait one minute so that thekdc-lin capacitors can discharge. Do not remove the cover until this time has elapsed.

All settings must only be entered by qualified personnel, paying particular attention to th safety precautions and warnings.

3.1 General

(1)The CombiDrive® does not have a main power switch and is therefore live when the mains supply is connected.

(2)When delivered, the inverter has a frequency setpoint range of between 0 Hz and 50 Hz. Regardless of its initial position, internal potentiometer R314 must be turned fully counter-clockwise before the CombiDrive® can be started.

R314 can be accessed by removing the right-hand gland hole cover (see Figure 3).

(3)Parameter settings can only be changed by using either the serial interface (SK200) or an optional Clear Text Display (OPm2). Refer to the parameter list in section 4 for a full description of each available parameter.

Connecting a serial link or the OPm2 to the serial interface is made simple by removing the appropriate gland hole cover (see Figure 3) and plugging a suitably terminated interface cable into the telephone socket

(SK200).

(4)Analogue input type selection is determined by jumpers JP300 and JP301. JP300 closed selects current input, JP301 closed (default) selects voltage input. These jumpers can only be accessed while the cover is removed (see Figure 3).

(5)If the CombiDrive® is run unloaded (e.g. for test purposes) and vibration or trip conditions occur, change P077 from 0 to 1 (requires OPm2).

3.2 Basic Operation

There are two basic modes of operation for the CombiDrive® . Neither mode requires the use of an OPm2 or serial link connection:

(1)Using the internal potentiometer only:

(a)For forward rotation, ensure that a link is fitted between DIN1 (pin 5) and P15+ (pin 8) on PL800 (see Figure 4a). For reverse rotation, connect the link to DIN2 (pin 6) instead of DIN1.

(b)Apply mains power. The green and yellow LEDs will illuminate to show that power is applied. Turn potentiometer R314 fully counter-clockwise, otherwise the CombiDrive® cannot be started.

(c)Turn the potentiometer clockwise until the yellow LED extinguishes. This indicates that power is now applied to the motor. Continue turning clockwise to increase the speed of the motor.

(d)Turn the potentiometer counter-clockwise to reduce the speed of the motor. Turning the potentiometer fully counter-clockwise causes the motor to slow to a complete stop. Check that both LEDs are illuminated (STANDBY mode).
