I am trying to integrate a Delta AS218RX-A PLC with a JMC IHSV42-40-07-24 Integrated AC Servo Motor using ISPSoft, but I am facing issues getting the motor to move using pulse/direction control.  
Setup:  
PLC Model: Delta AS218RX-A  
Servo Model: JMC IHSV42-40-07-24  
Software: ISPSoft  
Wiring Configuration:  
PUL+ → 24V  
PUL- → Y0.0 (Pulse Output from PLC)  
DIR+ → 24V  
DIR- → Y0.1 (Direction Output from PLC)  
ENA+ → 24V  
ENA- → Y0.2 (Enable Signal from PLC)  
PLC Program (ISPSoft):

SET Y0.2 ; Enable the servo motor  
PLSV 20000, Y0.0, Y0.1 ; Expected to move the servo in positive direction  
PLSV -20000, Y0.0, Y0.1 ; Expected to move the servo in negative direction  
Issue:  
When ENA- (Y0.2) is OFF, the motor holds its position firmly.  
When ENA- (Y0.2) is ON, the motor loses torque and becomes free, instead of getting ready to receive pulses.  
No motion occurs when I execute PLSV.  
No error alarms (ALM) appear on the servo.  
What I Have Checked:  
DIP Switch Settings:  
S1: ON, S2: OFF, S3: ON, S4: ON, S5: OFF, S6: OFF, S7: OFF, S8: OFF  
Pulse Output Mode (SR462) is set to 0:  
MOV K0, SR462  
Checked that Y0.0 and Y0.1 toggle properly in ISPSoft monitoring mode.  
Tried reversing the ENA- logic (connecting to 0V or 24V manually), no change.  
No fault or alarm on the servo motor.  
Questions:  
Has anyone successfully connected a Delta AS218RX-A PLC with a JMC IHSV servo motor?  
Could there be a logic inversion issue on ENA- or pulse/direction signals?  
Am I missing a parameter configuration in ISPSoft for pulse train output?  
Is there a way to check if the PLC is actually sending pulses on Y0.0?  
Any help would be greatly appreciated!
