F. Control Mode Selection (J6) – Jumper J6

is factory set to the “SPD” position for
Speed Control Mode . For Torque Control
Mode, set Jumper J6 to the “TRQ” posi-
tion. See Figure 22.

G. Torque Control Mode Selection (J7) –

Jumper J7 is factory set to the “S/L” posi-
tion for Speed Mode and Linear Torque
Mode. IMPORTANT: When J6 is set for speed control (“SPD”), J7 must be set to
“S/L” position (factory setting). For Non-
Linear Torque Mode, set Jumper J7 to the
“NL” position. See Figure 23. (See Section
VI, on page 18.)

H. Current Limit Mode Selection (J8) –

Jumper J8 is factory set to the “TCL” posi-
tion for Timed Current Limit operation. For
Non-Timed Current Limit operation, set
Jumper J8 to the “NTCL” position. See
Figure 24.

TCL (Timed Current Limit) – When
Jumper J8 is set to the “TCL” position, the
control will go into Stop Mode after it is in
overload for a predetermined amount of
time (set by the TCL trimpot).

Resetting the Control after TCL – To
reset the control after it has gone into TCL,
set the Start/Stop Switch to the “STOP”
position and then momentarily to the
“START” position or disconnect and recon-
nect the AC line. If the Start/Stop Switch is
jumpered (START and RET terminals con-
nected), the control must be restarted by
disconnecting and reconnecting the AC
line. If the Power On/Off Switch is
installed, set it to the “OFF” position and
then back to the “ON” position.

Warning!

When the control shuts down in

TCL, the AC line voltage is still
present in the control.

NTCL (Non-Timed Current Limit) –
When Jumper J8 is set to the “NTCL” posi-
tion, the control will not go into Stop Mode
after it is in overload.

Note: The TCL trimpot will have no affect
when Jumper J8 is in the “NTCL” position.

Stop Mode Selection (J9) – Jumper J9 is
factory set to the “RTS” position, for
Regenerate-to-Stop Mode. For Coast-to-
Stop Mode, set Jumper J9 to the “CTS”
position. See Figure 25.

J. Run Relay Output Mode Selection

(J10) – Jumper J10 is factory set to the “NO” position for normally open relay output con-
tacts at Terminal Block TB3. For normally closed relay output contacts, set Jumper J10
to the “NC” position. See Figure 26.
