Control Terminal Blocks Description and Control Logic

Control Terminal Block (TB3) Function

WARNING

To reduce risk of electric shock, severe

injury or death, allow machine power to remain off for three minutes minimum prior to working in and around AC drive. Proceed with caution.

W662

CAUTION

The controller is supplied with an internal power supply. Dry contacts or open collectors are required for discrete control inputs. If an external voltage is applied, component failure could occur.

W663

Input Mode Parameter

The control terminal functions are determined in part by the Input Mode parameter #46. Changing this parameter affects the function of some terminals. All machines equipped with A-B 160 drives use Input Mode “1”.

NOTE: If Input Mode is changed, power must be cycled to the drive for the change to take effect.

Speed Selection

Motor speeds on digitally-controlled AC drives are controlled by solid state or relay switch closure inputs to SW1, SW2, and SW3 in conjunction with STR and STF (direction) inputs. Refer to Figure 24 and Table 25.
