[PI Max Error]

Used with the process PI loop and sets the PI error value
which activates CR1-4 (if selected).The relay(s) will be ac-
tivated when [PI Error] exceeds this value.

“Acc/Dec Freq” 2

NOTE: Output frequency command of the drive directly at the output of the accel/decel ramp
generator. It does not include any modification due to selected speed regulation mode via [Speed
Control].

[Pulse Out Scale]

Provides a scaling factor for pulse output.

Pulse Output Rate = Hz x [Pulse Out Scale]

The pulse output will not provide a rate lower than 21 Hz.
A command less than 21 Hz will generate 0 Hz output. To
provide smooth operation across a wide speed range, se-
lect the maximum scale factor possible.

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]

Provides a scaling factor for the pulse input.

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]

Sets the delay time for the activation of the CR1-4 relays.
The relay is activated at Start + [At Time] seconds. This
delay affects all relays.

[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 [CR2 Out Select] is set to “Remote,” bit 1 of this parameter
will control CR2.

A Status description (bit ENUM) is displayed on line 1
(except Series A HIMs below version 3.0).
