Setup
Unit
range
0 to 500 % • You can set up the over-load level. The overload level becomes 115 [%]
<0> by setting up this to 0.
• Use this with 0 setup in normal operation. Set up other value only when
you need to lower the over-load level.
• The setup value of this parameter is limited by 115[%] of the motor rating.
0 to 20000 r/min • You can set up the over-speed level. The over-speed level becomes 1.2
times of the motor max. speed by setting up this to 0.
<0>
• Use this with 0 setup in normal operation. Set up other value only when
you need to lower the over-speed level.
• The setup value of this parameter is limited by 1.2 times of the motor
max. speed.
<Caution>
The detection error against the setup value is ±3 [r/min] in case of the 7-wire
absolute encoder, and ±36 [r/min] in case of the 5-wire incremental encoder.
Setup
Unit
range
0 to 32767 – You can setup the ratio between the encoder resolution and the external
scale resolution at full-closed control.
<0>
Encoder resolution per one motor revolution
External scale resolution per one motor revolution
• Pr78= <0> (default)
0 to 17 –
Numerator equals to encoder resolution, and you can setup
<0> the external scale resolution per one motor revolution with Pr7A.
• Pr78 ≠ 0,
Setup the ratio between the external scale resolution and the encoder
resolution per one motor revolution according to the above formula.
1 to 32767 –
<Caution>
<10000> • Upper limit of numerator value after calculation is 131072. Setup
exceeding this value will be invalidated, and 131702 will be the actual
numerator.
1 to 10000 16 x • You can setup the permissible gap (hybrid deviation) between the
<100> external present motor position and the present external scale position.
scale • The driver will trip with Err25 (Hybrid deviation excess protection) when
pulse the deviation is generated which exceeds the permissible gap.
0 to 1 – You can set up the logic of the absolute data of the external scale.
<0>
Setup value
<Caution>
When you use the linear scale by other manufacture than Mitutoyo,
position data will be kept as it is with the setup of 0, and it will become as
a reversed signed position data with the setup of 1.
