1 Operate the VFD67 drive from the keypad
Keypad mode is used to operate the drive completely from the keypad. This is the default setting of the VFD67 and this procedure is written as the drive would
be delivered from the factory.
STEP 1: (required) Ensure the control signals B2, B4, B5, and B6 are DISCONNECTED. (Drive modes will not change if these control signals are connected).
STEP 2: Wire the mains and motor, and power the drive (See Figure 1).
STEP 3: Use the MODE key in combination with the UP and DOWN keys on the keypad to set parameters 1 to 4 for the desired frequency limits
and ramp values. (See front cover of the VFD67 drive for parameter descriptions).
STEP 4: Set Pr 05 to PAd (default setting).
STEP 5: Set Pr 06 to motor rated current.
STEP 6: Press the MODE key button (2 times) on the keypad until is displayed.
STEP 7: Close or jumper terminal B2 to B4. (See Figure 2). Display will change from to
STEP 8: Press the green START key on the drive keypad to run the drive (The display will read and the motor will be at zero speed).
STEP 9: Press the UP key to increase the speed, press the DOWN key to decrease the speed. The STOP/RESET key is used to stop and reset the
drive.
2 Operate the VFD67 drive with a 0 to 10Vdc control signal
STEP 1: (required) Ensure the control signals B2, B4, B5, and B6 are DISCONNECTED. (Drive modes will not change if these control signals are connected).
STEP 2: Wire the mains and motor, and power the drive (See Figure 1).
STEP 3: Use the MODE key in combination with the UP and DOWN keys on the keypad to set parameters 1 to 4 for the desired frequency limits
and ramp values. (See front cover of the VFD67 drive for parameter descriptions).
STEP 4: Set Pr 05 to (this is the analog voltage mode).
STEP 5: Set Pr 06 to motor rated current.
STEP 6: Wire the control terminals (See Figure 3).
3 Operate the VFD67 drive with a 4-20mA control signal
STEP 1: (required) Ensure the control signals B2, B4, B5, and B6 are DISCONNECTED. (Drive modes will not change if these control signals are connected).
STEP 2: Wire the mains and motor, and power the drive (See Figure 1).
STEP 3: Use the MODE key in combination with the UP and DOWN keys on the keypad to set parameters 1 to 4 for the desired frequency limits
and ramp values. (See front cover of the VFD67 drive for parameter descriptions).
STEP 4: Set Pr 05 to (this is the analog current mode).
STEP 5: Set Pr 06 to motor rated current.
STEP 6: Wire the control terminals (See Figure 4).
