Function selector - digital inputs

Function selector of the digital inputs

All digital inputs of the controller are set by way of a function selector. The selector assigns each input a function.
The two inputs ISDSH and ENPO "Enable Power" are reserved for the hardware enable. For the touchprobe function the two "fast inputs" ISD05 and ISD06 are available. Settings (-5) to (-1) are reserve for use as an analog input.

Function

P 0101-

P 0107

MPRO_INPUT_FS_ISD00 Digital inputs
(0) OFF Input without function
(1) START Start of closed-loop control
Motor is energized. The direction of rotation depends on the reference
(2) INV Invert reference
(3) STOP Quick-stop as per quick-stop reaction (Low active)
(4) HALT The ongoing axis movement is interrupted and resumed as per the "HALT" reaction following resetting.
(5) LCW Limit switch evaluation without overrun protection, positive direction. The reaction to limit switch overrun and to interchanged limit switches can be preset.
(6) LCCW Limit switch evaluation without overrun protection, negative direction. The reaction to limit switch overrun and to interchanged limit switches can be preset.
(7) INCH_P Jog in positive direction
(8) INCH_N Jog in negative direction
(9) HOMST Start homing: according to the homing method parameterized in
P 02261 MPRO_402_Homing Method
(10) HOMSW Reference cam to determine the zero for positioning
(11) E-EXT Error messages from external devices cause an error message with the reaction determined in parameter
P 0030 Error-Reaction (11)
(12) WARN External collective warning

(13) RSERR

Error messages are reset with a rising edge if the error is no longer present In some special case it is necessary to restart the device in order to reset an error. Note the settings in the "Error reactions" subject area.

(14) MAN In field bus operation switching of the reference source
P 0165 CON_CfgCon and the control location P 0159 MPRO_CTRL to "Term" can be set via a digital switch.
(15) PROBE Touchprobe: The function can only be executed via the fast inputs ISD05 and ISD06 in conjunction with PLC or CANopen/EtherCAT.
(16) PLC Input can be evaluated by PLC program
(17) PLC_IR Interruption of the PLC program
(18) MP_UP Motor potentiometer: Increase reference value
(19) MP_DOWN Motor potentiometer: Decrease reference value
(20) HALT_PC Feed stop with subsequent position control
(21) TBEN Import and execution of selected table driving set
(22) TBTEA

Teach-in for position references

The current position is stored in the specified table index on a rising edge.

The index can be defined via the inputs in binary format (setting 23-26) or set via parameter P 0207. The teach-in function can also be activated by parameter P 0269- MPRO_TAB_Ctrl bit 0.

(23) TAB0 Binary driving set selection (bit 0) , (significance 20) for speed
(24) TAB1 Binary driving set selection (bit 1), (significance 21) for speed or positioning
(25) TAB2 Binary driving set selection (bit 2), (significance 22) for speed or positioning
(26) TAB3 Binary driving set selection (bit 3), (significance 23) for speed or positioning
(27) EGEAR Engage electronic gearing
(28) REFANAEN Enable analog reference
(29) ENC Use of ISD05 / ISD06 as encoder input (pulse count, pulse/direction).
(30)-(32) Software-specific  
(34)-(35)

JOG_EXT_POS
JOG_EXT_NEG

Jog mode in positive and negative direction.

(36) FAST-DISC Fast discharge of DC link (using a braking resistor)
(37) LIM_OFF Scaling of torque
(P 0332 TmaxScale) and speed limitation
(P 0337 SmaxScale) is disabled (ISDxx = "high"). If the function is not parameterized to an input (ISDxx = "low") the limits are always active.
(38) LOCK_POS Reversing lock, positive direction (access also via iPLC).
(39) LOCK_NEG Reversing lock, negative direction (access also via iPLC).
(40) EMC_BRK Emergency brake, direct engagement of holding brake
(41) PWR_RELAIS Manual switching of precharge relay (use only after consultation with LTi DRiVES GmbH).
