Armature
Current
(IA CAL)
Note the maximum armature current from the motor rating plate and set this value using SW1, SW2 and SW3.
The switches set Amps in hundreds, tens and units. The illustration shows an IA CAL setting of 77A.
Field
Current
(IF CAL)
Note the nominal field current from the motor rating plate and set this value using SW4, SW5 and SW6. The
switches set Amps in tens, units and tenths. The illustration shows an IF CAL setting of 5.7A. The maximum
current is 19.9A, setting a higher value than this results in 0A.
Armature
Voltage
(VA CAL)
Set this using the 4-way
switch, SW7. The switch
sets voltage according to
the table. The illustration
shows a VA CAL setting of
200V.
(A “1” indicates that
the switch is ON).

2.2
CONNECT THE AUXILIARY SUPPLY:
Remove 3-phase fuses (
6
). Re-instate branch circuit protection or circuit
breaker (
8
). Check that the auxiliary voltage is correct. The MMI will now display the Welcome screen.
AUXILIARY POWER ONLY IS CONNECTED AT THIS STAGE
Use a digital voltmeter to check for +24V rail at terminal C9, +10V rail at terminal B3, -10V rail
at terminal B4. The drive will be using the default speed feedback option ARM VOLTS FBK.
