Figure 2.44 Baseblock Operation during Run
Setting A: Accel/Decel Ramp Hold
When the contact input programmed for the Accel/decel ramp hold function closes, the drive will lock (“hold”) the
output frequency. Acceleration or deceleration will resume when the input is reopened.
If the Accel/decel ramp hold function is enabled (d4-01 = 1), the drive will save the output frequency to memory
whenever the Ramp Hold input is closed. When the drive is restarted after stop or after power supply interruption, the
output frequency that was saved will become the frequency reference (provided that the Accel/decel ramp hold input is
still closed). Refer to d4-01: Frequency Reference Hold Function Selection on page 144 for details.
Setting B: Drive Overheat Alarm (oH2)
Triggers an oH2 alarm when the contact closes. Because this is an alarm, drive operation is not affected.
Setting C: Analog Terminal Input Selection (Analog Inputs 1, 2)
When closed, the terminals specified in H3-14 are enabled. When open, the drive disregards the input signal to the analog
terminals.
Setting E: ASR Integral Reset
Switches between PI control and P control by resetting the integral value. As long as the terminal is closed, integral
operation is disabled and the drive uses P control. When the terminal opens, PI control resumes.
Setting F: Through Mode
Select this setting when using the terminal in a pass-through mode. When set to F, an input does not trigger any function
in the drive. Setting F, however, still allows the input status to be read out by a PLC via a communication option or
MEMOBUS/Modbus communications.
Setting 10, 11: Up, Down Command
Using the Up/Down function allows the frequency reference to be set by two push buttons. One contact input must be
programmed as the Up input (H1- = 10) to increase the frequency reference, and the other one must be programmed
as the Down input (H1- = 11) to decrease the frequency reference.
The Up/Down function has priority over the frequency references from the digital operator and the analog inputs (b1-01
= 0, 1). If the Up/Down function is used, then references provided by these sources will be disregarded.
