Control Terminal Blocks Description and
Control Logic
Control Terminal Block (TB3) Function
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.

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.

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.
