7.1 Initial settings - without power
The suggested Comissioning strategy is to start in the safest possible mode of operation and
progressively exercise each element of the system until full functionality has been achieved.
For this reason, all drive units are shipped to run using the:
1.
Set the following switches:
• Select the current range using switches S1 and S2 - set to
the minimum motor rating that includes the motor rating
current. Refer to "Figure 6 User adjustments" on page 10.
• Set switches S3 and S4 to OFF to select feedback full scale at
100%, 50 V.
• Set switches S5, S6 and S7 to provide the desired relay
function -
Refer to "Figure 6 User adjustments" on page 10
• Set switch S8 to ON to select Armature Voltage, and the Tach
from T9 must be disconnected.

MAX CURRENT
Set the MAX CURRENT from your motor rating
plate - clockwise rotation of the potentiometer
gives 0-100% current limit. For example, 50%
rotation provides a 50% current limit for the
selected current range set by switches S1 and S2.

Links - ensure that:
a. The link for the MAX CURRENT potentiometer mode is in the POS I/
NEG I position.
b. The 4Q TORQUE/2Q TORQUE/SPEED link is in the SPEED position.
c.
1S and ZS QUENCH links are fitted.
• highest supply voltage option at nominal speed • ARMATURE VOLTAGE feedback mode
• lowest speed range
• lowest current range
To avoid damage, ensure the supply selection jumper on the drive matches the
incoming ac supply
