â– [Ao2] terminal output PWM/pulse output adjustment
ï‚Ÿ When PWM output is selected for "[Ao2] Terminal output selection [C027]" ([C027] = 00 to 02,
04 to 07, 10, 12), the output gain can be set with "[Ao2] Gain adjustment [C105]".
ï‚Ÿ When "Digital current monitor (08)" is selected for [C027], set the reference value of the output
pulse with "[Ao2] Terminal reference frequency [C030]". The pulse is outputedtt in proportion so
that the output current value set for [C030] is to be 1,440 Hz.
When "Pulse input monitor (15)" is selected for [C027], output pulses can be adjusted with
"Pulse input/ monitor output scale convert gain [C047]".
(Output pulse frequency = Input pulse frequency x [C047])
[Ao2] Output
reference value
When "Digital current monitor (08)" is selected
for [C027], the current value that makes the
[Ao2] terminal output 1,440 Hz is set.

When "Pulse input monitor (15)" is selected for
[C027], scale conversion is applied to the input
pulse frequency and the converted value is

Output pulse frequency
= [C047] × input pulse frequency
Sets the gain of the [Ao2] terminal output.

(Example 1) PWM output for output frequency monitor ([C027] = "Output frequency (00)")
ï‚Ÿ PWM output is 100% output when output frequency is at the maximum frequency. Since the full
scale of "Output frequency" is the maximum frequency, the gain setting is left at the default
value of 100%.
â–
(Example 2) PWM output for output current monitor ([C027] = "Output current (01)")
ï‚Ÿ PWM output is 100% when output current is at the rated output current. Since the full scale of
"Output current (01)" is 200% of the rated output current, setting "[Ao2] Gain Adjustment
[C105]" = 200% results in 100% PWM output at the rated current output.
(When the maximum
frequency setting = 60 Hz)
