TOMATECH AUTOMATION
Adjust the relevant parameters based on the active level of the connection signal, zero
return
type and direction applied:
BIT5 (DECI) of the bit parameter No.004: active level of deceleration signal in machine
zero
return.
BIT0, BIT1, BIT2，BIT3，BIT4 (ZMX, ZMZ, ZMY，ZM4, ZM5) of the bit parameter No.006:
X, Z,
Y, 4th, 5th axis machine zero return mode B or C selection.
BIT0, BIT1, BIT2, BIT3, BIT4 (ZCX, ZCZ, ZCY, ZC4, ZC5) of the bit parameter No.007:
whether a
proximity switch is taken as both deceleration and zero signals.
BIT2(ZNLK) of the bit parameter No.011: whether the direction key in zero return is
self-locked.

Ⅲ Connection
BIT0, BIT1, BIT2, BIT3, BIT4(ZRSCX, ZRSCZ, ZRSCY, ZRSC4, ZRSC5) of the bit
parameter
No.014: have/not the machine zero(zero turn mode BC/A)setting bit.
Data parameter No.033: low deceleration speeds of each axis in machine zero return.
Data parameter No.113: high speed of each axis in machine zero return.
BIT0, BIT1, BIT2, BIT3, BIT4(MZRX, MZRZ, MZRY, MZR4, MZR5) of the bit parameter
No.183:
each axis zero return direction: negative or positive.
Only the stroke limit switch validity is confirmed, can the machine zero return be
performed.
The machine zero is usually fixed at the max. travel point, and the effective stroke of the
zero
return touch block should be more than 25mm to ensure a sufficient deceleration distance
for
accurate zero return. The more rapid the machine zero return is, the longer the zero return
touch
block should be. Or the moving carriage will rush over the block and it may affect the zero
return
precision because of the insufficient deceleration distance.
Usually there are 2 types of machine zero return connection:
① The connection to AC servo motor: using a travel switch and servo motor one-turn
signal
separately
Fig. 4-2
By this connection, when the deceleration switch is released in machine zero return, the
one-turn
signal of encoder should be avoided to be at a critical point after the travel switch is
