Analog controller output (Package Q, Option Q: setting 'ANALOG/PWM')
Parameter 58
F/P contr.output
----------------
Package Q, Option Q only
f controller: output range see below
If Parameter 54 has been configured to "ANALOG" this parameter must be confi-
gured to the appropriate type of analog controller. The range of the analog output is
configured here. To switch from a current to a voltage or PWM output a jumper
must be added to terminals 8/9. The ranges are listed below

NOTE
The control logic of the PWM signal can be inverted by following steps:
- Select "F/P contr.type" (Parameter 54) = ANALOG.
- Select with Parameter 58 "F/P contr.output" any of above inverted control outputs
(e.g
. "10 to 0mA (5 to 0V)", "4.5V to 0.5V", "20 to 0mA (10 to 0V)" or "20 to 4mA").
- Back up one screen (Parameter 54; by pressing "Select" and "Cursor→" simultaneously).
- Select "F/P contr.type" (Parameter 54) = PWM.
Now
the PWM signal is inverted.
Parameter 59
Level PWM
----------------
Package Q, Option Q only
f controller: PWM level 3.0 to 10.0 V
If PWM has been selected in Parameter 58 the level of the PWM signal can be ad-
justed here.
Parameter 60
Stepper sign.frq
(min.) 000%
Package Q, Option Q only
f controller: minimum value 0 to 100%
This parameter permits the operator to clamp or limit the lower analog output val-
ue.
Example:
A 1 to 4V analog output is needed for the voltage controller to operate
properly. A jumper is installed on the terminals as described above and the analog
output of 0 to 5V is selected. The number to be configured in this parameter is de-
termined by dividing the desired lower limit by the range (1/5=0.20 or 20%). 20%
is the value to be configured in this parameter.
