Digital I/O
[PI Max Error]
This parameteris used withthe process PIloop and sets
thePI errorvaluewhichactivatesCR1-4 (ifselected).The
relay(s) will be activated when [PI Error] exceeds this
value.
Parameter Number 293
Parameter Type Read Only
Display Units / Drive Units 0.01 Hertz / 32767 = Maximum Freq Forward
Factory Default Maximum Freq Forward
Minimum Value –400.00 Hz
Maximum Value 400.00 Hz
[Pulse Out Select] – Stand-Alone Version Only
Thisparameter selectsthe sourcevaluethatdrivespulse
output.
Parameter Number 280
Parameter Type Read and Write
Factory Default “Output Freq”
Units Display Drive Range
“Output Freq” 0 See [Output Freq]
“Encoder Freq” 1 See [Encoder Freq]
“Acc/Dec Freq” 2 See Note
Note: Output frequency command of the drive directly at the output of the accel/decel ramp gen-
erator. It does not include any modification due to selected speed regulation mode via [Speed
Control].
[Pulse Out Scale] – Stand-Alone Version Only
Provides a scaling factor for pulse output.
Pulse Output Rate = Hz x [Pulse Out Scale]
The pulseoutput will notprovide arate lower than21 Hz.
Acommand lessthan 21Hzwill generate0Hz output.To
provide smooth operation across a wide speed range,
select the maximum scale factor possible.
Parameter Number 281
Parameter Type Read and Write
Display Units / Drive Units Factor / Factor
Factory Default 1
Minimum Value 1
Maximum Value 64
Example:
[Pulse Out Select] is set to “Output Freq” and drive is programmed for [Maximum Freq] = 60 Hz.
When the drive output is 60 Hz, the Pulse Output Rate is adjustable from 60 Hz (60 x 1) to 3840
Hz (60 x 64).
[Pulse In Scale] – Stand-Alone Version Only
Provides a scaling factor for the pulse input.
Parameter Number 264
Parameter Type Read and Write
Display Units / Drive Units Factor / Pulses per Rev
Factory Default 64 PPR
Minimum Value 1
Maximum Value 4096
Example:
4 Pole Motor, 60 Hz = Max. Speed.
The 1336-MOD-N1 option outputs 64 Hz/Hz. At full analog reference, the pulse input to the drive
will be 60 Hz x 64 Hz/Hz = 3840 pulses/sec.
[At Time]
Setsthedelaytimeforthe activationoftheCR1-4relays.
The relay is activated at Start + [At Time] seconds. This
delay affects all relays.
Parameter Number 327
Parameter Type Read and Write
Display Units / Units 0.01 Second / Seconds x 100
Factory Default 0.00 Sec
Minimum Value 0.00 Sec
Maximum Value 360.00 Sec
[Remote CR Output]
Individual bits control relay outputs when selected with
[CR1-4 Out Select]. 1 = Energize Coil. This parameter is
reset to the default on power-up.
Example:
If[CR2OutSelect]issetto“Remote,”bit1ofthisparameter
will control CR2.
A Status description (bit ENUM) is displayed on line 1
(except Series A HIMs below version 3.0).
