P0681 – MOTOR SPEED IN 13 BITS
Range: - 32768 to 32767
Properties: RO
Access groups
via HMI:
Description:
It allows monitoring the motor speed. This word uses 13-bit resolution with signal to represent the motor
synchronous speed:
P0681 = 0000h (0 decimal)

P0681 = 2000h (8192 decimal)

Intermediate or higher speed values in rpm can be obtained by using this scale. E.g. for a 4 pole motor and
1800 rpm of synchronous speed if the value read is 2048 (0800h), then, to obtain the speed in rpm one must
