Analog Command Hold Function
• While the AHD terminal is turned on, the Inverter keeps external analog input results on hold.
• While the AHD terminal is turned on, you can use the UP/DWN function based on the reference
value of the analog signal kept on hold by this function.
• If UP/DWN selection C101 is set to "01", the Inverter can store an UP/DWN result.
• If the power is turned on with the AHD terminal turned on, or if the RS terminal is turned on and
then off, the Inverter employs the data kept on hold immediately before.
Note1: If the control function is switched via the SET/SET3 terminal with the AHD terminal turned
on, the set frequency is retained. To change the control function, turn off the AHD terminal
once, and keep the analog signal on hold again.
Note 2: If this function is frequently used, the internal storage element service life may be shortened.
Multi-function Pulse Counter (PCNT, PCC)
• The Inverter can input pulse trains via a multi-function input.
• With pulse counter monitor d028, you can monitor the total count of input pulses.
• The total pulse count value cannot be stored. After the power is turned on or after reset, the counter
is reset to zero.
• Turning on PCC (pulse counter clear) clears the total count value.
• The input pulse frequency resolution can be obtained with the following formula. (This applies to
pulse input with a 50% duty ratio.) The Inverter cannot input frequency higher than the specified
frequency resolution. It is recommended that you use input frequencies up to 100 Hz. For details
on input terminal response, refer to "Input Terminal Response Time" (page 4-105).

Frequency resolution (Hz) = 250/(Input terminal response time set values C160 to C168 + 1
Example: When the input terminal response time = 1, the frequency resolution = 125 Hz.
