WARNING!
When power is applied to the drive,
ALWAYS use an insulated tool when adjusting the presets.
Refer to the Supply Selection
table on page 11.
AC power is applied when lit.
Rotate clockwise to increase
current. S1 and S2 select the
range.
Rotate clockwise to increase
response. Excessive rotation
may cause instability. If rated
motor motor voltage is much
lower than AC supply then
anticlockwise is prefered.
Rotate clockwise to increase
level of armature voltage
droop compensation.
Excessive rotation may cause
instability. Always set fully
anti-clockwise in Tacho mode.
Rotote clockwise to increase
drive deceleration from 1 to
30 seconds - note that
natural coast down is a limit.
Rotate clockwise to increase
drive acceleration from 1 to
30 seconds.
Rotate clockwise to increase
minimum speed.
Use to adjust 4-20 mA loop
burden resistor between 0
and 390 Ω if 4-20 mA mode
is selected.
Rotate clockwise to
increase speed. Change the
range with S3 and S4.
Drive quenches when lit if stall timer trips - the
time depends upon the current demand:

RELAY
FUNCTION
Select the function of the internal relay:
S5 - when ON, the relay remains energised
until a stall condition occurs.
S6 - when ON, the relay is energised for
speeds 5% of full scale.
S5 & S6 - when both ON, the relay
de-energises when a stall condion occurs
AND the motor speed has fallen below 5%
of full scale.
S7 HOLD
When ON, the drive will power up in a stall
condition. It may be be reset by momentarily
shorting pad T61 to pad T62.
S8 TACH/AVF
Select the speed feedback source:
When ON, ARMATURE VOLTAGE is selected (default).
When OFF, TACHO is selected.
With a jumper in TORQUE position, terminal 6 is a torque input.
With a jumper in SPEED position, terminal 6 is a direct speed input.
