Pressing the Mode will store the new setting and also exit the PROGRAM mode. To change another
parameter, press the Mode key again to re-enter the PROGRAM mode (the parameter menu will
be accessed at the parameter that was last viewed or changed before exiting). If the Mode key is
pressed within two minutes of exiting the PROGRAM mode, the password is not required access the
parameters. After two minutes, the password must be entered in order to access the parameters again.
4.2.1 Setting Values in Tenths of Units Above 100
Parameter settings and the keypad speed command can always be adjusted in tenths of unit
increments from 0.0 to 99.9. Above 100 however, values can be set in whole units or tenths of units,
depending on the setting of Parameter 16 - UNITS EDITING.
If Parameter 16 - UNITS EDITING is set to WHOLE UNITS (02), parameter values and the keypad speed
command can only be adjusted by whole unit increments above 100. For example, Parameter 19 -
ACCELERATION TIME could not be set to 243.7 seconds. It could only be set to 243 or 244 seconds.
Likewise, the keypad speed command (set using the
p
and
q
buttons) could not be set to 113.4
Hz. It could only be set to 113 or 114 Hz.
If, however, Parameter 16 - UNITS EDITING is set to TENTHS OF UNITS (01), parameter values and the
keypad speed command can be adjusted in tenths of unit increments up to a value of 1000 (above
1000, whole unit increments only). Each push of the
p
or
q
button will adjust the value by one
tenth of a unit. If the p or q button is pressed and held, the value will increment by tenths of units
until the next whole unit is reached, and then the value will increment by whole units.
When a value above 100 is being adjusted by tenths of units, the value is shifted to the left by one
digit so that the tenths portion of the value can be displayed. This results in the first digit (reading
from left to right) of the value disappearing from the display. Also, the lower decimal point will blink
to indicate that the actual value is above 100. Once the value is no longer being adjusted, the value
will shift back to the right and the tenths portion of the value will disappear.
In the example below, Parameter 19 - ACCELERATION TIME is presently set to 243.0 seconds, and is
being increased to 243.7 seconds.
