Speed Compensation (cont’d)
Speed Comp Units Speed compensation is programmed by entering the response time of the output de-
vice in milliseconds (.001 Sec). The output will always turn on this number of msec
before the programmed ON position is reached, and turn off this number of msec be-
fore the programmed OFF position is reached. As speed increases, the number of
degrees of advance will automatically increase to maintain the number of msec of ad-
vance.
Programming To change output channels, move the cursor to the channel number and enter a new
one. You may also INC or DEC the channel number.
To change speed comp values, use the numeric keys or INC and DEC. To enter tenths
of msec, use the decimal point. When entering even msec, the decimal point is not
needed: “12 ENT” will result in a value of 12.0.
Negative Speed Comp Negative values of speed compensation cause an output channel to lag its programmed
machine position by the specified number of msec. See Section 4 for details on apply-
ing negative speed compensation.
To program negative speed comp, press the +/- key after entering a number but before
pressing ENT. You may also decrement a value below zero.
NOTE: Regardless of the number of outputs available, speed compensation is limited
to any 16 of those available outputs.

COMP MODE
Purpose For units with the “-L” option (Leading/Trailing Edge Speed Comp), Speed Comp Mode
determines whether standard or leading/trailing edge speed compensation is in effect.
Screen
When the Speed Comp Mode is ONE, the same value of speed comp is used for both
leading and trailing edges.
When the Speed Comp Mode is “L/T”, the leading and trailing edges of a pulse may
have different values of speed comp.
Programming Press the SEL key to toggle between ONE and L/T. Press ENT to confirm your selec-
tion.

have same speed comp; L/T = Each edge can have
a different value of speed comp.
