10.4.4 Value range of PWM outputs
Normally, only a PWM ratio between 5 % and 95 % is required.
To adapt the output range of the PWM output the parameters 1601 / 1606
PWMOutx_RefLow and 1602 / 1607 PWMOutx_RefHigh are to be used. The limit val-
ues may be specified directly in per cent PWM ratio.
Parameterising Example:
Actual speed 2000 Speed is to be read out via the PWM output 1 by a pulse-pause ratio
of 5 % ... 95 %. The range is to be restricted to 500 rpm - 1500 rpm, i.e., 500 rpm will
correspond to 5 % and 1500 rpm to 95 % PWM ratio.

1600 PWMOut1_Assign 2000
1601 PWMOut1_RefLow 5 %
1602 PWMOut1_RefHigh 95 %
1603 PWMOut1_ValueMin 12.5 %
1604 PWMOut1_ValueMax 37.5 %
10.4.5 Error monitoring of PWM outputs
PWM outputs are monitored during cable breaks, short circuits and overcurrents. Moni-
toring and parameterising of PWM outputs is heavily dependent on the electric charac-
teristics of the connected load.
Monitoring of cable break, short circuit and overcurrent is activated with the parameters
51x0 DOPWMx_SupviseOn activates monitoring of output x
The error message may be delayed by means of the parameter
111x0 DOPWMx_DelayTime delay time until error message
This means that the error state must remain active for at least the time set in this param-
eter before an error message is generated.
Monitoring is possible only when both the high-phase and the low-phase of
the PWM signal are greater than 137.5 µs. Delay time must be adjusted to
