Parameter Switching Function For Reverse Operation - YASKAWA CIPR-CR70A Series Technical Manual

*1 Set S1-54 to S1-56 = 0 [Disabled] when you do not use the brake sequence.
Note:
• When the 3 motors are used, a protective function set in L1-01 [Motor Overload (oL1) Protection] is applied to motor 1 and motor 2
only. For motor 3, set up a thermal overload relay between the drive and motor 3, so that the sequence trips an external fault (coast to
stop).
• You cannot switch between V/f patterns during run for motor 3. Even when b1-23 = 1 [Selection REV Parameters = Enabled], the
drive will not switch between motors even when the counterweight signal is input.
• If the frequency reference exceeds the maximum output frequency, then it will still be limited by the maximum output frequency set to
each motor. For example, if you set E1-04 = 60 Hz, E3-04 = 50 Hz, d1-04 [Reference 4] = 60 Hz, and d1-04 as the part of multi-step
speed reference, then the frequency reference for motor 1 will be 60 Hz, and 50 Hz for motor 2.
• Refer to the following for the default settings change as the control method.

Note:
When H1-xx = 16 and/or 39, the drive does not detect oPE08 [Parameter Selection Error] concerning contradictory settings in the
MFDIs, MFDOs, analog inputs, and monitor outputs. The drive recognizes terminals that have not been set to a function as "Not Used".

Parameter Switching Function for Reverse Operation

This function allows the application to switch between the torque compensation delay time, the mid point a
voltage, and the minimum output voltage. The conditions for switching are based on the input terminal status and
the direction of the Run command (forward or reverse), along with the parameter setting combinations.
Set the following parameters when using this function.
• Set b1-23 = 1 [Selection REV Parameters = Enabled].
• Set H1-xx = 38[MFDI Function Selection = Counterweight Selection].
Note:
The switching function is disabled during run.

Switches between motors 1 and 2.
ON: Selects motor 2
OFF: Selects motor 1
Switches to motor 3. It is necessary to set H1-xx = 16 when setting H1-xx =
39. If H1-xx = 39 is set while H1-xx = 16 is not set, oPE03 [Multi-Function
Input Setting Err] is detected.
ON: Selects motor 3
OFF: Clears the selection of motor 3
