Operating Functions
• Use this parameter to select the FIR filter time constant used for the command pulses (FIR: Finite
impulse response).
• The higher the setting, the smoother the command pulses.
• If the setting is 0, the control cycle will be (0 + 1)
× 166 = 166 μs.
If the setting is 1, the control cycle will be (1 + 1)
× 166 = 332 μs.
Likewise, if the setting is 31, the control cycle will be (31 + 1)
× 166 = 5,312 μs.
Explanation of Settings
• If Pn4E is set to 0, the minimum time width of the ECRST signal will be as follows:
