(6) DRIVE SPEED change function
You can change a SCAN DRIVE or INDEX DRIVE speed to any desired speed while the drive is taking place.
(This feature, however, is not available when different time constants are specified for the acceleration
and deceleration at INDEX DRIVE.)
(7) ADDRESS COUNTER function
The ADDRESS COUNTER counts the absolute address of the pulse output from the MCC05v2 and allows to read
the count data any time as needed.
(8) PULSE COUNTER function
The PULSE COUNTER can always read out output pulses and 90゜phase difference clocks or CW/CCW independent
clocks from the servo driver and read out count data. Five COMPARE REGISTERs are connected to the PULSE
COUNTER, so this permits detecting an optional count value.
(9) DIFFERENTIAL COUNTER function
The DIFFERENTIAL COUNTER counts deviation between the output pulse and the 90゜phase differentiated
external clock or the mutually independent external CW and CCW clocks. It allows to read the count data
any time as needed.
Two COMPARE REGISTERs on the DIFFERENTIAL COUNTER enables to detect any deviation level.
Other than determining deviation level, this counter offers independent counting of the external 90゜phase
differentiated clock or the mutually independent external CW and CCW clocks.
(10)Function for fast/slow stop by LIMIT STOP
Two stop types using the LIMIT signal, namely, fast and slow, are available and can be specified by
user program.
(11)Function for the servo driver
A function for the END signal and deviation COUNTER RESET signal of the servo driver is provided.
(12)Interrupt generating function
An interrupt can be generated for the PCI bus master.
RDYINT interrupt ……… Interrupt request signal(RDYINT) that is generated upon termination of a command.
CNTINT interrupt ……… Interrupt request signal(CNTINT) that is generated at an optional count value of
the PULSE COUNTER.
DFLINT interrupt ……… Interrupt request signal(DFLINT) that is generated at an optional count value of
the DIFFERENTIAL COUNTER.
IOINT interrupt ……… Interrupt request signal(IOINT) that is generated upon additional inputs ON or OFF.
(13)ORIGIN DRIVE function using the limit sensor
The ORIGIN DRIVE using the limit sensor is available, too.
(14)Current speed read function
You can read current speed during the drive.
(15)Setup data read function
It allows you to read the user program specified settings for HSPD, LSPD, RATE, SPEC INITIALIZE and such.
