Data unit :
Data range : 0 to 32767
Standard setting : 0
Set convert coefficient (numerator, denominator) in case of using multiplyed
feedback signal of motor sensor (Mi sensor or MZi sensor) by gear ratio as
spindle position feedback signal.
When the motor rotates P times for Q rotation of the spindle, setting
parameters are ( P and Q are disjoint sets integral number)
No.4171 (No.4173 in case CTH1A=1) = P
No.4172 (No.4174 in case CTH1A=1) = Q
When this parameter is set to 0, handle as it set to 1.
4.3 Procedure for setting parameters related to detector
The setting of the parameters used for typical detector cofigurations is
described below.
With αi series spindle, the detector circuitry hardware is set by parameter
setting. This means that alarms such as disconnection or overheat alarms
may be output while parameter related to detector are being set.
To initialize the hardware, briefly turn off the amplifier power after setting
the parameters related to detector.
Described Parameter Nos. are 16i/16’s.
