OL[N] - Output Logic
Purpose:
Defines the logic level and function behavior of the digital outputs. The drive has several
non-committed digital outputs. Each of these outputs can be programmed to a specific
function and logic level.
Each OL[N] entry is dedicated to a certain output: OL[1] for the DOUT1 connector pin
and OL[2] for the DOUT2 connector pin, … OL[N] for the N connector pin
The following table summarizes the functions that can be attached to the digital output
pin.
OL[N] Bits Meaning Values
0: Low level active. 0 Logic levels
1: High level active.
0: General purpose. Serves as a simple digital output
function, subject to the OB[N] or OP setting.
1: AOK, drive ready for use.
2: Brake. Responds according to definition in BP[N].
3: Motor enable/disable indication. 1 - 4
4: Reserved.
5 - 15 Reserved
Table 3-31: OL[N] Functions
Terms:
Logic level low:
When the function is active, the opto-coupler is conducting.
Logic level high:
When the function is active, the opto-coupler is open circuit.
AOK:
Indicates that the drive is ready. The AOK signals that the physical conditions needed
to run the motor are available. If AOK is flagged, the motor DC voltage is within
range, the drive temperature is good, and no over-current or short-circuit has been
captured during the previous 10 milliseconds. When programming this option,
OB[N] and OP have no influence on the relevant output.
Brake:
The output is mapped to brake functionality as defined in BP[N]. When
programming this option, OB[N] and OP have no influence on the relevant output.
The brake function works only in positive logic.
Motor Enable/disable
The output is mapped to this function as defined in the MO command. When
programming this option, OB[N] and OP have no influence on the relevant output.
