15 Speed 2-Wire Operating Mode

Operation in the 15 Speed 2-Wire mode is controlled by the opto isolated inputs at J4-8

through J4-16. The opto inputs can be switches as shown in Figure 3-27 or logic signals

from another device.

Switched inputs at J4-11 through J4-14 allow selection of 15 preset speeds and provide

Fault Reset as defined in Table 3-9.

Refer to Figure 3-35.

J4-8 CLOSED allows normal control operation.

OPEN disables the control and motor coasts to a stop.

J4-9 CLOSED operates the motor in the Forward direction (with J4-10 open).

OPEN motor decels to stop depending on Keypad Stop mode.

J4-10 CLOSED operates motor in the Reverse direction (with J4-9 open).

OPEN motor decels to stop depending on Keypad Stop mode.

J4-11-14 Selects programmed preset speeds as defined in Table 3-9.

J4-15 CLOSED selects ACC / DEC / S-CURVE group 2.

OPEN selects ACC / DEC / S-CURVE group 1.

J4-16 If J4-16 is connected, you must set Level 2 Protection block, External Trip to

“ON” to activate the opto input.

CLOSED allows normal control operation.

OPEN causes an external trip fault. The control will disable and the motor

coasts to a stop. An external trip fault is displayed (also logged in the fault log).
