Points of use:
· This module (NP1F-MP1/NP1F-MP2) outputs response signal to the read command sent from the CPU module.
By the response to read command, handshaking can be performed between the CPU module and this module.
· While the response to read command is “1,” this module (NP1F-MP1/NP1F-MP2) continuously rewrites data in
current value data areas 1 and 2. (For the following registers, the read value changes dynamically.)
1) Current frequency register
2) Command pulse register
3) Deceleration point register (when automatic deceleration point calculation is enabled)
4) Error monitoring timer
5) Command pulse counter
