Function Input variable Description
bUp_b DIGIN_bln1_b
(digital input of the
terminal X5)
TRUE - The signal atn nOut_a approaches its max. limit value (nHighLimit).
wTir - Acceleration time . The time can be set under code C0262.
nHighLimit - Limitation of the max. speed setpoint. The limit can be set under C0260.
nDown_b DIGIN_bln3_b TRUE - The signal at nOut_a approaches its min. limit value.
wTif - Deceleration time. The time can be set under code C0263.
nLowLimit - Limitation of the minimum speed setpoint. The limit can be set under C0261.
blnAct_b DIGIN_bln2 OR
DCTRL_blmp_b
TRUE - ’byFunction = 3’: The motor potentiometer changes its output immediately to 0%
(important for the emergency-off function)
DCTRL_blmp_b TRUE - if the controller sets pulse inhibit.
dnActRetain Saves the last output value of nOut_a after mains failure
byInitFunction(=2) The output value = 0% is loaded when the mains is switched on.
MCTRL_bQspOut_b Quick stop (QSP)
MCTRL_nSet_a Speed setpoint for motor control
DIGIN_bln4_b TRUE - A trip (error) will be reset.
Processing in the cyclic task. Project file: ’Constant_and FCODE_assignment (PRG)’
