PARAMETERS

Note: 1. This function is only valid in the external operation mode. This function is not activated when "1"
or "2" (remote setting function) is selected for Pr. 59.
2. If the current averaging zone includes the low output region, the output current may increase in
the constant-output region. When the current is low, the running frequency increases, increasing
the deceleration time.
3. The maximum output frequency is 120Hz. If its setting exceeds 120Hz, the output frequency is
120Hz.
4. The fast-response current limit function is invalid.
5. Can be activated at every start.
6. When the terminal functions are changed using Pr. 180 to Pr. 186, the other functions may be
affected. Confirm the functions of the corresponding terminals before making settings.
CAUTION
When the load is light, the motor may accelerate suddenly up to 120Hz, causing
hazardous conditions. Provide sufficient interlocks on the machine side before
starting operation.
z Set frequency reference table for load torque high-speed frequency control
The following table lists the frequencies set when the load torque high-speed frequency control signal (X19)
and multi-speed terminals (RH, RM, RL) are selected together:
Input Signals
X19 RH RM RL

{ Conforms to load torque high-speed frequency control.
{ Speed 1 (high speed) Pr. 4
{ Speed 2 (middle speed) Pr. 5

Setting using terminal 2, 1, 4, JOG
{ indicates that the signal is on.
Note: 1. Assumes that the external operation command mode is selected and the remote setting function
is not selected.
2. Multi-speeds override the main speeds (across terminals 2-5, 4-5, 1-5).
3. When the 12-bit digital speed input (option FR-A5AX) is selected, the above list is invalid.
(The 12-bit digital speed input has the highest priority.)
4. Jog operation overrides the above list.
