Description of the digital inputs
No function.
0, Off
Software reset of the servo amplifier in the event of a fault. All the functions and displays are set to the initial
1, Reset
status. Parameters that are not stored in the EEPROM are erased, the parameter set that is stored in the
EEPROM is loaded.
If any of the error messages F01, F02, F03, F05, F08, F13, F16 or F19 are present, then no software-reset will
be carried out, just the error message will be deleted. This means that, for example, the encoder output signals
are stable and can continue to be evaluated by the controls.
2, PSTOP
Limit-switch function. A LOW signal on the input terminal PSTOP (terminal X3/13) inhibits the positive direction
of rotation (clockwise, when looking at the motor shaft, at the A-end of the motor: parameter ROTARY
DIRECTION positive). The motor brakes (with emergency ramp), and stands with the I-component under
control, mechanical disconnection (stop) is not permitted.
A falling edge releases the brake, the 0V level disables the negative setpoint.
Limit-switch function. A LOW signal on the input terminal NSTOP (terminal X3/14) inhibits the negative direction
3, NSTOP
of rotation (counterclockwise, when looking at the motor shaft at the A-end of the motor: parameter ROTARY
DIRECTION positive). The motor brakes (with emergency ramp), and stands with the I-component under
control, mechanical disconnection (stop) is not permitted.
A falling edge releases the brake, the 0V level disables the positive setpoint.
4, PSTOP+Intg.Off
Limit-switch function. A LOW signal on the input terminal PSTOP (terminal X3/13) inhibits the positive direction
of rotation (clockwise, when looking at the motor shaft, at the A-end of the motor: parameter ROTARY
DIRECTION positive). The motor brakes (with emergency ramp), and stands without the I-component under
proportional control, mechanical disconnection (stop) is permitted.
A falling edge releases the brake, the 0V level disables the negative setpoint.
5, NSTOP+Intg.Off
Limit-switch function. A LOW signal on the input terminal NSTOP (terminal X3/14) inhibits the negative direction
of rotation (counterclockwise, when looking at the motor shaft at the A-end of the motor: parameter ROTARY
DIRECTION positive). The motor brakes (with emergency ramp), and stands without the I-component under
proportional control, mechanical disconnection (stop) is permitted.
A falling edge releases the brake, the 0V level disables the positive setpoint.
6, PSTOP+NSTOP
Limit-switch function STOP, regardless of the direction of rotation. A LOW-Signal on the input terminal PSTOP
(terminal X3/13) or NSTOP (terminal X3/14) inhibits both directions. The motor brakes (with emergency ramp),
and stands with the I-component under control, mechanical disconnection (stop) is not permitted.
A falling edge releases the brake, the 0V level switches the internal speed setpoint to 0V.
Limit-switch function STOP, regardless of the direction of rotation. A LOW-Signal on the input terminal PSTOP
7, P/Nstop+Intg.Off
(terminal X3/13) or NSTOP (terminal X3/14) inhibits both directions. The motor brakes (with emergency ramp),
and stands without the I-component under proportional control, mechanical disconnection (stop) is permitted.
A falling edge releases the brake, the 0V level switches the internal speed setpoint to 0V.
8, An In 1/An In 2
Switches over the setpoint inputs An In ½. This function is only effective if the analog setpoint function
0,Xcmd=An In 1 has been selected.
High level at the input: Setpoint input 2 (terminals X3/6,7) is active
Low level at the input: Setpoint input 1 (terminals X3/4,5) is active
