7.1.3 Speed Reference Parameters (Group 2)
The following sections (7.1.3.1 and 7.1.3.2) and parameter descriptions describe the
method of selecting the speed reference for each of the drive models. The following
items apply to all models:
•
When using the jog function (P-11 = 2) , the Internal/Jog Frequency (P-40) is
used, thus overriding P-20 (Main Speed Reference) and P-21 (Alternate Speed
Reference). See the description of P-11 (Configurable Input) for more information.
•
If the keypad is the selected speed reference (P-20 = 1 or P-21 = 1) and the
connection between the keypad and the drive is bad or not present, a Bad Keypad
Connection fault (CL) will be generated.
7.1.3.1 Selecting the Speed Reference for Model A and Model B Drives
Figures 7.1 and 7.2 show the logic that is used to establish the source of the speed
reference for model A and model B drives. See the parameter descriptions for
additional configuration information.

Use this parameter to define the turn
on/off threshold for the configurable
output. Its definition and units depend
on P-12 (Configurable Output).

•
If P-12 is set to 0, 1, 2, or 3, this parameter is not used.
•
If P-12 is set to 4, the user relay turns on when the commanded frequency exceeds this value in Hz.
•
If P-12 is set to 5, the user relay turns on when the output current exceeds this value in amps.
