A426 [Keypad Freq] Related Parameter(s): P047, P049, P051
Provides the drive frequency command using the built-in keypad navigation. When P047, P049 or P051 [Speed Referencex] selects 2 “Keypad Freq”, the value set in this parameter
controls the frequency of the drive. The value of this parameter can also be changed when navigating with the keypad by pressing the Up or Down arrow keys.
Values Default: 60.00 Hz
Min/Max: 0.00/500.00 Hz
Display: 0.01 Hz
A427 [MOP Freq]
Provides the drive frequency command using the built-in Motor Operated Potentiometer (MOP).
Values Default: 60.00 Hz
Min/Max: 0.00/500.00 Hz
Display: 0.01 Hz
Frequency is not written to non-volatile storage until drive is powered-down. If both MOP Up and MOP Down are applied at the same time, the inputs are
ignored and the frequency is unchanged.
A428 [MOP Reset Sel]
Determines if the current MOP reference command is saved on power down.
Options 0 “Zero MOP Ref” Resets the MOP frequency to zero on power down and stop.
1 “Save MOP Ref” (Default)
A429 [MOP Preload]

Options 0 “No preload” (Default)
1 “Preload” Bumpless Transfer: whenever MOP mode is selected, the current output value of the speed is loaded.
A430 [MOP Time]
Sets the rate of change of the MOP reference.
Values Default: 10.0 s
Min/Max: 0.1/600.0 s
Display: 0.1 s
A431 [Jog Frequency] Related Parameter(s): P044
Sets the output frequency when a jog command is issued.
Values Default: 10.00 Hz
Min/Max: 0.00/[Maximum Freq]
Display: 0.01 Hz
A432 [Jog Accel/Decel]
Sets the acceleration and deceleration time used when in jog mode.
