1.5 Hz to 9.8 KHz [K1 to K9800 (units: Hz)] (Max. error near 9.8 kHz approximately -0.9 kHz)
* Set “K1” to specify 1.5 Hz.
48 Hz to 100 KHz [K48 to K100000 (units: Hz)] (Max. error near 100 kHz approximately -3 kHz)
191 Hz to 100 KHz [K191 to K100000 (units: Hz)] (Max. error near 100 kHz approximately -0.8 kHz)
( * 3): Target value (Absolute value) (Can be specified for only Ver. 2.0 or later.)
This is used when setting the target value match stop mode. (Absolute only)
Designate the target value setting in the range indicated below. If an out of range value is
designated, the number of pulses output will be different than the desinated value. The target
value setting is ignored in the no count mode.
Output method Range of target values which can be designated
Addition counting Designate a value larger than the current value.
Subtraction counting Designate a value smaller than the current value.
